Recommended use of ambulatory blood pressure and ECG recorders
Indications for ambulatory ECG monitoring
The following indications are listed for non-pediatric patients in the ACC/AHA
Guidelines for Ambulatory Electrocardiography, 1999.
1. To assess symptoms possibly related to rhythm disturbances
 Patients with unexplained syncope, near syncope, or episodic dizziness in whom the
cause is not obvious
 Patients with unexplained recurrent palpitation
2. To assess antiarrhythmic therapy
 To assess antiarrhythmic drug response in individuals in whom baseline frequency of
arrhythmia has been well characterized as reproducible and of sufficient frequency to
permit analysis
 To detect proarrhythmic responses to antiarrhythmic therapy in high-risk patients
3. To assess pacemaker and ICD function
 Evaluation of frequent symptoms of palpitation, syncope, or near syncope to assess
device function so as to exclude myopotential inhibition and pacemaker-mediated
tachycardia and to assist in the programming of enhanced features such as rate
responsivity and automatic mode switching
 Evaluation of suspected component failure or malfunction when device interrogation
is not definitive in establishing a diagnosis
 To assess the response to adjunctive pharmacological therapy in patients receiving
ICD therapy
NB: there is no pacemaker spike detector in CardioTens recorders.
4. Ischemia monitoring
 Patients with suspected variant angina
Indications for ambulatory blood pressure (ABP) monitoring
The following indications are listed in the European Society of Hypertension
recommendations for conventional, ambulatory and home blood pressure measurement,
2003.










Suspected white-coat hypertension
Suspected nocturnal hypertension
To establish dipper status
Resistant hypertension
Elderly patient
As a guide to antihypertensive drug treatment
Type 1 diabetes
Hypertension of pregnancy
Evaluation of hypotension
Autonomic failure
As CardioTens and card(X)plore are combined recorders, they offer special benefits in
patients where indications apply for both ambulatory ECG and ABP monitoring.
4
Contraindications







Non-cooperative patients, unconscious or otherwise incapable patients
Patients requiring urgency / emergency cardiac care
Patients with a sensitivity / allergy to adhesive ECG electrodes
Patients with coagulation disturbances (for ABP monitoring)
Patients with serious mobility or other impairments without supervision
Children without supervision; children younger than 8 years (ABP monitoring)
Though the blood pressure measurement algorithm used in ABP devices has been
found to function properly on patients with atrial fibrillation or other common
arrhythmias, the oscillometric blood pressure measurement method is generally
recommended for use only with special caution in case of patients with arrhythmias,
Parkinson's disease, or other diseases with tremor
Safety concerns
Electric shock hazard protection
Meditech recorders meet relevant shock hazard protection standards. Ambulatory blood
pressure (ABP) and combined recorders operate with 2/4 1.5V AA batteries or 2/4 1.2V
AA rechargeable batteries (2 AA size batteries for ABPM-05). Event and holter ECG
recorders operate with a single AAA battery. This excludes all electric shock hazards,
even in the unlikely case of multiple device errors. Use only standard long-life (alkaline)
batteries, or standard NiCd or NiMH rechargeable batteries of the proper size. Do not
use lithium batteries. Do not mix different battery types or new and old batteries.
Keep a safety distance of at least 2 meters from any electric devices, metallic objects or
other electric conductors during application and removal of ECG electrodes. As long as
any patient lead cables (with electrodes) are applied to the patient, not yet applied or
disconnected lead cables must not contact potential shock hazard sources or electric
conductors, as such contact may, through applied electrodes, serve as a pathway for a
potentially life-threatening electric shock.
Many personal computers do not meet certain shock hazard protection standards or strict
safety regulations applicable to medical devices. Therefore, during the computer-based
use of Meditech recorders, keep at least a 2 meter distance between patient and
computer. Meditech recorders communicate using a plastic optical cable, whose 4 m
standard (and up to 10 m optional) length allows the required safety distance. The
plastic optical cable ensures perfect electric separation and reduces the effects of
external electric noise. It does not conduct electricity.
Risk of incorrect diagnosis
The basic intended use of Meditech recorders is to record ECG signals and blood
pressure values. Recorded ECG quality depends mainly on electrode contact quality and
recording conditions, so valuable recordings are to be expected from properly instructed
cooperative patients, using properly applied, high quality electrodes. Patients should be
informed about the rules of cooperative behaviour, proper handling of the recorder used,
and expected results of monitoring in advance. ABP and ECG recorders only provide
data to support diagnostic decisions of a qualified physician, they do not automatically
provide a diagnosis of any kind. During the evaluation of recorded ECG, possible
artefacts due to external disturbances, motion artefacts, and electrical noise should be
observed and handled with caution.
5
Working with Meditech recorders
The recorder must be programmed from the CardioVisions software installed on the
computer. Once the pre-programmed time is reached, the recorder will commence
operating automatically and perform blood pressure measurements and/or record ECG
signals based on the monitoring plan. To obtain reliable BP readings and high clarity
ECG signals, certain rules must be observed.
Rules of monitoring
1. Inform the patient about the goal and expected results of the monitoring. Provide an
event diary and rules to observe.
2. Patients should not wear synthetic clothes during ECG monitoring, as this may
cause disturbances in ECG recordings due to static electricity and small discharges.
3. Patients can fit the recorder comfortably with the adjustable straps.
4. It is advisable to wear a thin shirt or blouse under ABP cuffs. This does not
influence the accuracy of blood pressure measurement, but it prevents problems
caused by long-time wear of the cuff (sweat, itching, soreness, etc.).
5. The cuff and/or electrodes should be properly placed and connected. Good electrode
contact requires skin preparation and electrodes designed for long-term application.
6. Should an electrode become disconnected, it, or a new electrode of the same type
should be re-applied to the same position as soon as possible.
7. Patients should avoid excess movement during blood pressure measurements. They
should hold their arm loose, slightly away from their chest.
8. Should blood pressure measurements cause bloodshots, torpidity or pain in the
hand, the cuff should be removed from the arm immediately and disconnected from
the recorder. Such occurrence should be reported to the physician latest after the
monitoring session.
9. Patients may start extra blood pressure measurements with the START button of
ABP recorders. They should mark events such as taking medication, waking up or
going to sleep with the EVENT button. They may interrupt any single blood
pressure measurement if necessary by pressing either button of ABP recorders.
10. Patients should not remove the recorder even at night. By loosening the straps, they
can avoid problems when turning in their sleep. The recorder does not disturb most
patients at night. Removing a card(X)plore recorder will (even if the electrodes and
cuff remain connected) result in the loss of actigraphy data.
11. Should the batteries run down during a monitoring session, they can be simply
replaced. Monitoring will continue, and data will not be lost. The memory card
should not ever be removed during monitoring from card-capable recorders.
12. Patients should never measure anybody else’s blood pressure with an ABP recorder
during an ambulatory blood pressure monitoring session.
For detailed information on recorders, please read the Meditech recorder guide.
6
Monitoring step by step
Before you begin, you must have the CardioVisions software properly installed and
configured on your computer, and the recorder correctly connected. To program your
recorder, you will need a Meditech optical interface cable properly connected to your
computer's USB or serial port (or to a USB port using a standard USB-to-serial
converter) and the communication port correctly selected in the CardioVisions software.
To transfer data to your database after a monitoring session from a CardioMera or
card(X)plore recorder, you will also need an SD memory card reader unit, preferably an
USB2-type reader, connected to your computer. The memory card necessary for
monitoring is by default supplied with the recorder itself. As different computer
configurations may require different card reader models, and many computers come
originally equipped with one, a memory card reader unit is by default not supplied with
a card-based Meditech recorder, but is readily obtainable from local sources.
A successful monitoring session consists of the following steps:
1. Inform your patient about monitoring rules well in advance.
2. Insert the necessary number of fully charged, proper size batteries into the
battery compartment and check their voltage.
3. Insert memory card properly into the card slot (where applicable).
4. Start the CardioVisions program, select the preferred recorder type for use.
5. Enter new patient data or select patient from the database.
6. Apply the cuff and/or electrodes to the patient.
7. Connect the recorder to the computer and check electrode placement.
8. Create a monitoring plan (possibly containing blood pressure measurement
intervals, ECG monitoring settings and event auto-detection trigger limits).
9. Send the monitoring plan from the computer to the recorder unit.
10. Give detailed instructions to the patient who has to wear the recorder.
--- Monitoring session (typically 24 hours) --11. Check if the plan is completed.
12. Remove the unit, cuff and electrodes from the returned patient.
13. Ask for the patient diary, and ask the patient for any events,
symptoms, observations or complaints.
14. Start the CardioVisions program and select the proper recorder type for use.
15. If you use a CardioMera or card(X)plore recorder, remove the memory card
from the recorder and insert it into the card reader unit of your computer.
16. Transfer collected data from the recorder or card to your database.
17. Analyze ECG curves, blood pressure profile, ST trends, etc.
18. Create and print a report.
7
Using the CardioVisions software
The CardioVisions software package provides means to handle Meditech ambulatory
blood pressure and ECG recorders as well as the data collected by such recorders. From
CardioVisions it is possible to initialize (program) a recorder, check ECG signal quality
of an ECG recorder applied to a patient in real time mode, and transfer (read) collected
data from a recorder to your computer. CardioVisions stores data transferred to the
computer in its database for easy future access. The database offers user access control,
organizing patient data in folders similar in appearance to those used for normal
document storage, but with a high degree of safety for sensitive medical data. It also
offers a comfortable archive-and-restore feature for a safe backup of large size holter
ECG recordings. CardioVisions provides detailed graphical and tabular displays of
recorded data, a comprehensive set of editing features and full statistical analysis, all in
a highly customizable user interface. Its efficient report generator and editor can create
standard reports automatically, but also allows for free editing of any report component
like a word processor.
In summary, CardioVisions lets you:
 manage (select, initialize and read data from) recorders
 browse patients and the results of monitoring sessions in a database
 view, edit and analyze data in a recording
 create, save and print a freely editable report.

CardioVisions editions and system requirements
Personal and Network Edition
CardioVisions comes in two different editions.
CardioVisions Personal Edition can be installed on a single computer and used only by
one user at a time. The use of ABPM devices is possible without registration with an
unlimited number of recorders. If used with CardioTens and event recorders without
software options, the CardioVisions Personal Edition can be used completely without
registration up to 10 recorders total. The use of more than 10 recorders, other recorder
types (Holters), network edition use and ECG analysis functions require registration.
Multiple users can work with one database in a computer network at the same time
using CardioVisions Network Edition. This edition has to be installed on a server
computer in a network, where users have access to CardioVisions services over the
network from the workstations. CardioVisions Network Edition requires registration
(see under registration section).
Using the Personal Edition for demo purposes
Demo data in CardioVisions Personal Edition are specifically included so that all
features which would otherwise require registration will still work in an unregistered
installation, but on the special demo data only. The network functionality is not included
in this, so there is no demo feature of the CardioVisions Network Edition.
Computer requirements
CardioVisions can be installed on most Windows-based personal computers, but please
check before installation whether your computer meets the following requirements.
Minimum Requirements
CPU
RAM
VGA
HDD
LAN
OS
Suggested Configuration
350 MHz Pentium II
2 GHz P4 or equivalent
64 MB
512 MB
800x600 @ 16 bit color
1024x768 @ 16 bit color
about 40 MB for the software + disk space for database *
10 Mbit/s
100 Mbit/s
Windows 98 SE / Me / 2000 / XP
*
The disk space necessary for the database depends on recorder type, number of
patients and number of examinations. Typically, it takes 75 MB to store 1000 ABPM
recordings without reports. ABPM recordings are small; holter ECG recordings may
require up to 80 MB each. The installation of demo data requires about 200 MB, too.
Please note that certain features of CardioVisions, especially the ECG annotation,
require a lot of calculations, so the faster your computer, the shorter time you will need
to get a 24-hour ECG recording analyzed. If your computer meets the minimum
requirements only, it may take several minutes to complete the ECG annotation
procedure. Data transfer time will depend on the reader you use, or over a network, they
will depend on your network connection speed.

Installation and first start
As with any software installation, you need a proper access level to the computer on
which you want to install CardioVisions. Especially with the Network Edition to a
server, this usually means Windows system administrator access.
If you wish to use CardioVisions on a single stand-alone computer, the proper choice is
CardioVisions Personal Edition. If you wish to store your database on a server computer
and access CardioVisions on any workstation in a networked environment, possibly with
several users working with the software at the same time, you will need to install
CardioVisions Network Edition. Do not install both editions on the same computer.
Remember that the Network Edition will not work at all without a proper registration, so
if you just want to try CardioVisions, install the Personal Edition on a computer. Both
editions are available on the installation CD accompanying a Meditech monitoring
system. You can always download the latest release of CardioVisions from the Meditech
website at http://www.meditech.eu.
Installing CardioVisions Personal Edition
If you have an installation CD, insert it into your CD drive and (provided the auto-run
feature is not disabled) you will see a start screen where you can select which edition
you wish to install. If the auto-run feature is disabled, open the CD folder and run
(double-click) the setup.exe program, then select the Personal Edition to install. The
selection will start a typical installation wizard. If you downloaded the Personal Edition
installer from the Meditech website, start the installer directly.
Before you install CardioVisions, you need to go through the typical steps, as follows:
 Choose language to install
 Accept licence agreement
 Choose components to install
 Choose recorder type(s) you want to use
 Choose target folder of installation
 Choose Start menu folder for startup icon placement
The default installation language of CardioVisions will be that of your Windows system
(if such a language version of CardioVisions is available), but setup offers you to choose
another language from a list. To install CardioVisions, you must first carefully read and
accept the licence agreement, which you can also read at the end of this manual. Then
you can select the options you wish to install; necessary components include the
CardioVisions software itself, plus small demo data for ABPM and event recorders. You
may choose to install or omit demo data for combined and holter recorders as well; this
requires additional disk space, of course. In the next step, you can select which recorder
type(s) you wish to use with CardioVisions. All compatible Meditech recorders are
listed and checked by default – just remove the tick-mark from the checkboxes of the
recorder types you do not want to use. Then you will be asked to select the target folder
of the installation. CardioVisions will by default be installed in your Program Files
folder, in a Meditech subfolder, and finally a subfolder with the appropriate
CardioVisions release version information. If you have a previously installed earlier
version of CardioVisions, the setup wizard will locate it for you and will offer to install
10
the new version to overwrite the old one. This will not influence your database, or any
program settings – they will be preserved from your previous installation. This happens
only if you install the new CardioVisions to the same folder where the old installation is
located. If you select another target folder, you will have two different CardioVisions
installations with independent databases, which may cause confusion and should
therefore be avoided. Before you perform an upgrade, as with all software, it is
advisable to create a safety backup of your existing installation. In the next screen of the
setup wizard, you can choose a Start menu folder where setup will place the usual
shortcuts for CardioVisions: a startup icon, a help icon and an uninstallation icon. By
default this is the Meditech folder of your Start menu. After finishing the setup the
installation will proceed. Wait until you see a screen prompting you to finish the
installation. CardioVisions setup will place a startup icon on your desktop as well.
Installing CardioVisions Network Edition
If you wish to access CardioVisions functions from several workstations in a computer
network, you have to install CardioVisions Network Edition. The installation procedure
looks quite similar to that of the Personal Edition (see above), but the result is rather
different. While Personal Edition setup installs a typical program where you have a
single executable file to start and then you can access all functions, the Network Edition
setup will install two separate applications, two executable files: one for the networked
CardioVisions database engine application (also called the database server), and another
for the so-called CardioVisions client application, i.e., the user-end of the program to
ask for data over the network from the database engine on any workstation. Therefore,
the Network Edition has to be installed on a properly configured server computer. After
the installation, the CardioVisions database engine will be automatically started by
default whenever the server computer is started. The Network Edition has to be installed
on the server computer, on the individual workstations only a shortcut has to be created.
Then, as a result, the database engine will run on the server computer continuously, and
the CardioVisions client can be started on any workstation with a proper shortcut
(startup icon). For all normal user purposes, the CardioVisions client of the Network
Edition is indistinguishable from the program used in the Personal Edition. There is one
important difference in behaviour, however: if you use the Network Edition and the
server computer is shut down, it will not be possible to start CardioVisions from the
workstations, of course. Similarly, even if the server computer is switched on, but the
CardioVisions database engine is not running (it is stopped, shut down or not started at
all), it will be impossible to use CardioVisions.
Compared to the installation of CardioVisions Personal Edition, there is one additional
step to take before installation of the Network Edition. After you choose the recorder
type(s) to use, you will be asked to select an IP-address (a network property) through
which the database engine can communicate with the client(s) running on any
workstation. This is a question only if the server has multiple network adaptors, either
for intra- and extranet purposes, or because of different physical subnets.
To complete your CardioVisions Network Edition installation, you have to manually
share the “CLIENT” folder of your installation with read-only access from all
workstations and you have to create a shortcut on each workstation pointing to the
CardioVisions client application executable file in this folder (its name is CV001.EXE).
11
This is best done manually as automatic sharing is either impossible or could have
serious security risks, and once the shortcut is created, you can simply “copy-paste” it to
all workstations where you want to use CardioVisions. If in doubt, consult your
computer network administrator.
It is possible to configure your CardioVisions database engine application to use
different options in the unlikely case of networking problems. However, the database
engine is an auto-configuring application, so change a working configuration only if it is
absolutely necessary and always with the close assistance of an experienced network
specialist. To change database engine configuration, first request all users to log out
from CardioVisions and close all CardioVisions clients on all workstations, then bring
up the database engine application from the system tray on the server computer by
double-clicking its icon, then choose Server – Stop, then select the required command of
the Config menu. After your changes, choose Server – Start to make the CardioVisions
database engine services available to users again.
Installation results: folders, shortcuts and programs
After a successful installation, CardioVisions Personal Edition setup places a startup
icon (a shortcut) with the proper name and version number on you desktop. The
necessary files will by deafult be installed in a Meditech folder under your Program
Files folder. Setup places a folder with a similar name in your Start menu, by default
under the Meditech folder there. In this Start menu folder, you will find a startup icon
(shortcut) for CardioVisions, another shortcut for CardioVisions Help, and a third
shortcut for the removal (uninstallation) of CardioVisions. You can start CardioVisions
either with the desktop startup icon, or with the one in your Start menu.
If you install CardioVisions Network Edition, you will find the same folders and icons,
plus in the proper Start menu folder you will find an additional shortcut for the
CardioVisions database engine. CardioVisions setup will place another shortcut of the
database engine in the Autostart folder of your Start menu, to ensure that the
CardioVisions database engine is automatically started whenever the server computer is
switched on. Setup will also automatically start the database engine when it is
successfully finished. An icon in the system tray of the server computer will show that
the CardioVisions database engine is running.
The “CLIENT” folder of your CardioVisions Network Edition installation has to be
shared for read-only access for everyone manually, and a shortcut properly pointing to
the CV001.EXE program in this shared folder has to be created on the workstations.
12
First start
After a successful installation, you can start CardioVisions with the proper startup icon
(shortcut). Apart from the need for the database engine to run in the background on a
properly configured server computer in a Network Edition installation, there is no major
difference from a user point of view between the Personal and Network Editions, so
unless otherwise noted, the following information applies to both Editions.
When you first start CardioVisions, you will be logged in as a CardioVisions system
administrator, and a first start wizard will guide you through the following steps to
personalize your installation:



Finish registration
Please note that these settings can be modified later during the regular use of
CardioVisions, but are necessary to start with from the beginning, so some steps above
are a must before you start.
CardioVisions system administrator settings
After a welcome screen on first startup, CardioVisions will ask for the CardioVisions
system administrator's login name and password. Please note that these can (and maybe
should) differ from your general Windows administrator properties. The input boxes for
both the login name and the password will be admin by default. Please change this to
your preferred admin login name and password to prevent system security problems.
Write your preferred admin login and password down on a piece of paper, and lock it
away in a safe place. Do not lose the system administrator's login and password, or you
will be unable to access indispensable functions, such as registration, adding new users,
changing data access levels. The system administrator cannot view medical
measurement data nor edit reports. If you use CardioVisions Personal Edition on your
computer which only you have access to in a well protected environment, it may seem
overly cautious and therefore be annoying to have to use a password protection in
CardioVisions. Therefore it is possible to allow zero-length password for users in the
admin settings screen, by removing the tickmark from the password required box. This
does not mean that users cannot use a password if they like; it just means they may
choose to leave the password empty.
13
Adding a CardioVisions user
Because his tasks are mainly administrative and technical, the CardioVisions system
administrator by definition cannot open and view medical measurement data. Therefore
it is necessary to create at least one “normal” user in CardioVisions, sometimes this is
called a user account. More users can be added by the system administrator later; the
first startup procedure lets you – that is, requires you to – create only one. The bold
labels in this screen show that the last name, login name and password fields are
necessary to proceed, others are optional. If the password required checkbox has been
unchecked in the previous screen, it is possible to leave the password box here empty –
technically this is known as a zero length password. In this case the label of the
password box will not be bold. With the create icon on desktop checkbox it is possible
to create a personalized CardioVisions startup icon on the Windows desktop with the
name of the user just added here. The properties of such an icon will include the user's
login name so if CardioVisions is started with such a personalized shortcut icon, the user
will only have to type a password, or, if the password is empty, a shortcut so
personalized will log the user in directly to CardioVisions. Please note that this can
mean a serious data security risk if anyone else other than the intended user has access
to the computer, so use this possibility of comfort with extra caution only. The create
personal demo checkbox, if ticked, will create ABPM and event ECG demo data in the
user's own folder in the CardioVisions database. The create large ECG demo checkbox
will, if ticked, in addition, create holter and combined demo data there as well, requiring
extra disk space.
Users can – in fact, they are strongly advised to – change their password when they log
in to CardioVisions for the first time, with the password originally selected by the
system administrator during user account creation. If they choose to use no password
protection, that is, an empty (zero length) password. Users can change their password
any time using the New password command of the Tools menu in CardioVisions.
Report header
In this screen of the first start wizard it is possible to change the default report header
data to show data you would like to see on top of all printed report pages.
When you click the Next button after entering your report header details, CardioVisions
will create the user settings, the demo data and personalized icons. Therefore, it is not
possible to use the Back button after you click Next here. CardioVisions then takes you
to the second part of the first startup procedure – the registration.
14
Registering CardioVisions
In the second part of the first startup, the Registration Wizard will guide you through the
steps of registration. If used with ABP devices and event recorders without software
options, the CardioVisions Personal Edition can be used completely without registration
up to 10 recorders total. The use of more than 10 recorders, other recorder types,
network edition use and most complex analysis functions require registration. The first
recorder you manage with CardioVisions in such a case will automatically become your
key recorder, or key device. If you do not wish to register CardioVisions, exit the
wizard. You can start it later to register, or modify an existing registration, if you log in
as system administrator. Registration is required to use the Network Edition, access
certain functions or to receive technical support. The registration process consists of two
phases.
In the first, or request phase, follow the instructions of the Registration Wizard, and
send the resulting registration request by e-mail to Meditech (registration@meditech.hu)
directly, or ask your Meditech representative to do this for you. In this phase, you select
a recorder to be your “key device” that plays a part in the second phase of registration,
and in any other registration process that may follow.
In the second, or validation phase, you have to enter the response code you receive from
Meditech, and connect your key device to complete your registration. Please start
CardioVisions, log in as system administrator (user name: admin, password: admin),
start Registration from the Tools menu and follow instructions. Should the key device be
unavailable at this time, it can be connected later by any user. During any
communication with that recorder, the software will recognize the key device and the
registration process will be completed. If the key device is not connected at all, the
registration will not be validated, and will expire.
Registration welcome
In the first screen of the registration procedure you can decide to postpone the
registration until a later time if you click the exit without registration button (in the
Personal Edition only). In this case all limitations of non-registered use will remain in
effect as described above, so this is advised only if you just want to use CardioVisions
as a demo. If you have a Meditech recorder already, it is worth registering CardioVisions
now. Only registered users are entitled to product support. In this screen you can decide
whether you want to see normal or advanced registration options. Normal registration is
usually enough for any typical use of CardioVisions. You need to check the advanced
options checkbox only if you want to register more than ten units of any Meditech
recorder type. Otherwise normal registration is OK.
Registration – user information
In this screen you will be requested to enter contact information so Meditech will know
who the registered user is, where to send the registration response code necessary to
complete your registration, and who is entitled to product support. The institute, contact
person and e-mail boxes are necessary to proceed, others are optional. This information
will be used for sending the response code and to check if a product support request is in
order. This information might be forwarded to the Meditech representative responsible
for the area where the registration is requested, but in most cases you would purchase
Meditech recorders from that representative anyway. The information will not be
disclosed to anyone else and will not be used for any other purpose.
15
Registration – recorder types
In this screen you can select which supported recorder type(s) you wish to use with
CardioVisions. Please put a tick-mark in the checkbox(es) next to the recorder type(s)
you wish to use. Select the key recorder type from the list. Connect a Meditech recorder
of the proper type (with batteries in it) to your computer and click the Connect button in
the Key device frame. You can choose the serial communication line here as well, but
CardioVisions will automatically scan all available lines if it does not find a connected
recorder at the line checked first. When it finds a recorder of the selected type, it will
read the internally stored serial number of the unit and display it in the key device box
here. This means the recorder so connected now became your key device. You will need
the key device to complete (validate) your registration when you receive the response
code to your registration request. You will need the key device, too, if you later want to
modify your existing registration, e.g., by adding more recorder types or registering so
far unregistered components. Therefore, choose your key device with care, so that it is
not a recorder you just borrowed or not one you will probably lend or otherwise lose
from sight for a long time. If you use multiple recorder types, it is advisable to select a
key device of a recorder type that you meet frequently, e.g., an ABPM or a classic ECG
holter recorder.
To connect a Meditech recorder to your computer, you will need an interface. Most
Meditech recorders require a special optoelectronic interface cable; some can be
connected using Bluetooth wireless connection. See the chapter on interfaces on page
18 for details.
If you checked the advanced options checkbox in the registration welcome screen
previously, you can also set the requested number of recorders for any selected recorder
type. This is only necessary if you wish to register and use more than ten recorders of
the same type. Please remember that the registration fee for CardioVisions is based on
ten-recorder packages, so register more than ten recorders only if you really will use that
number, because this will mean a higher registration fee.
Registration – network
In CardioVisions Network Edition only, in this screen you will be asked to select the
number of active users for your CardioVisions system, meaning maximum how many
active users can exist and may log in to CardioVisions at the same time. The number of
active users will influence the total registration fee.
Registration – program components
After you specified your recorder type(s) and selected your key device, you will be
asked to select program components in this screen. Of all available program
components, only those associated with your selected recorder type(s) will be active.
Please put a tick-mark in the checkbox(es) next to the program components you wish to
register. Please note that some components may have prerequisites; e.g., you can register
the annotation editing component only if you have an annotation component registered.
You can register all available Holter program components if you click the select all
components for Holter button. Please remember that the registration fee for
CardioVisions depends very much on registered program components, so register only
those components you really wish to use.
16
Registration – remark
In this screen you can add any remarks associated with your registration request.
Registration – summary
In this screen you can review which recorder type(s) and which program components
you decided to register; what contact information you specified and what remark you
had. You can view the full status of your registration, or just your new request currently
being made with the radio buttons at the top; during the first startup they are the same,
of course, but if you decide to modify your registration later, this option might be useful.
With the e-mail / file only radio buttons below the summary you can decide whether you
want the just created registration request to be e-mailed immediately to Meditech or to
save it to a file on your computer only, to be sent to Meditech later. If you choose the
file only option, you can specify the target folder for that file in the box next to the
option. You can browse the folders on your computer to select the target folder for the
registration request file if you click the ... button here.
Registration – finish
In this screen CardioVisions informs you that you have successfully created (and
possibly e-mailed) your registration request. It reminds you that you will need to finalize
the registration procedure when you receive the response code. It also tells you where
you can find a copy of your registration request file.
When you click the Finish button after you created and possibly e-mailed your
registration request, you have completed the first startup procedure of CardioVisions
and are now in the main screen of the program. You are still logged in as the
CardioVisions system administrator, so you cannot start working with recorders and
patients. You can, however, use all system administrator tools, e.g., you can add new
users. If you want to start using CardioVisions for medical purposes, use the File –
Logout command then log in with the login name and password of the user you created
during the first startup.
Registration – validation phase
In the final, or validation phase, you have to enter the response code you receive from
Meditech, and connect your key device to complete your registration. Please start
CardioVisions, log in as system administrator, start Registration with the dedicated large
button or from the Tools menu and follow instructions. Should the key device be
unavailable at this time, it can be connected later by any user. During any
communication with that recorder, the software will recognize the key device and the
registration process will be completed. If the key device is not connected at all, the
registration will not be validated, and will expire after 1 month or 25 measurements.

Connecting a recorder to the computer: cable, wireless, card
You could connect Meditech recorders to the computer to the computer in the following
ways. Most Meditech recorders are equipped with a connector slot for a special
optoelectronic communication cable – with these recorders, the computer-end of the
interface cable has to be properly plugged into a corresponding socket on the computer
before inserting its small recorder-end plug into the socket on the recorder for
communication between the CardioVisions software and the recorder. Certain Meditech
recorder types are capable of wireless communication with the computer using
Bluetooth technology. For successful communication, Bluetooth settings of the
computer need to be properly adjusted. Some Meditech recorders are equipped with a
memory card slot. To transfer data from these recorders to the computer after a
monitoring session, the memory card be removed from the recorder and inserted into a
properly configured card reader unit.
Optoelectronic interface cable
To register a recorder as a key device, check electrode placement, send a monitoring
plan to the recorder, or transfer collected medical data to the computer, the recorder has
to be connected to the computer. Steps to follow for the first connection:
1. Locate a free 9-pin serial port (also called RS232, UART, often labeled OIO) or a
USB port (often labeled
) on your computer.
2. Take the optoelectronic interface unit with the optical cable out of the package.
In case of the serial interface cable, the interface unit is integrated in the serial plug with
the optical cable. The USB interface unit has a small USB plug (similar to a USB pen
drive) with an oblique socket for the independent optical cable.
3. Connect the interface unit to the port
If you have a serial RS232 port on your computer, just plug in the serial optoelectronic
interface. If you have a USB port on your computer, and you have a serial optoelectronic
interface, use a USB-to-serial converter. If you have a USB port on your computer and a
USB-type optoelectronic interface from Meditech, insert one end of the optical cable
into the miniature oblique optical socket on the USB interface dongle, matching the red
marks on the cable and on the interface label, then insert the USB plug into the USB
socket on the computer. It is advisable not to disconnect the optoelectronic interface unit
from the computer if it is used on that computer regularly.
4. Connect the recorder to the optical cable
Connect the small optical plug at the free end of the optical cable into the socket on the
the device matching red mark on cable to red mark on recorder labels. Insert and push it
gently until it clicks in place. Simply pull to remove. Do not pull the cable itself, always
handle the plug.
A recorder so connected is ready for communication with the CardioVisions software.
If you do not use the serial/USB port for other purposes, it is advisable to connect the
interface unit as described above only once, during first installation. Then the interface
unit with the optical cable is constantly connected to the computer, and only the free end
of the optical cable has to be inserted in the socket on the recorders to establish the
18
connection. The interface unit converts optical signals to electric ones and vice versa.
The twin optical cable transfers optical signals between the interface unit and the
recorder. The cable is flexible, but it is sensitive to overfolding and to cutting forces. If
you fold the optical cable in too small radius, or if a strong cutting force (e.g. by the
edge of a drawer) is applied to it, the optical cable may become optically distorted,
which might result in communication errors.
In the CardioVisions software, click the Tools menu, click the Options command, and
in the appearing Options dialog, select Communication on the left. On the right panel,
select the required recorder type, then select the Meditech USB or the Serial port
option as appropriate for the interface unit you have connected to the computer. To
check communication, connect the recorder (with batteries in it and switched on) to the
recorder-end of the optical cable, select the required port number or enable the Auto
search com port checkbox, and then click the Test button.
Wireless Bluetooth connection
CardioBlue is a recorder with wireless communication, and card(X)plore is optionally
available with wireless communication, too, both using Bluetooth(R) technology. Most
up-to-date computers today come with in-built Bluetooth capability, or are easily
extendible using a small USB Bluetooth dongle. Bluetooth functionality works
seamlessly in Windows XP Service Pack 2 or newer releases, but it usually can be added
to older Windows versions as well. Windows XP Help, as well as the documentation of
Bluetooth dongles, contain detailed information how wireless devices can be used, and
this is described in detail in CardioVisions Help as well. However, if you use
CardioBlue, you may need the following information during the first startup procedure
after the installation of CardioVisions.
If you wish to use a CardioBlue or a card(X)plore with Bluetooth recorder under
Windows XP SP 2, follow the steps below. With other Windows versions, please refer to
the documentation of the Bluetooth device used in your computer.
1. If you wish to use a wireless, Bluetooth-capable Meditech recorder, open the Tools Options dialog of CardioVisions and select the Communication category. Select the
type of the recorder, then click on the appearing Bluetooth settings button. In the
appearing dialog, click on the Connect setup button to go to the next step.
2. In the appearing dialog you can see Meditech recorders which have already been
added to your computer. Place fresh batteries into the new (CardioBlue or
card(X)plore with Bluetooth) recorder and make it Bluetooth discoverable.
[For this, in case of CardioBlue, press and hold the button of CardioBlue for more
than 3 seconds but less than 8 seconds and then release it. The Bluetooth LED of the
CardioBlue emits green light, indicating the recorder is discoverable.
In case of card(X)plore press and hold both buttons of card(X)plore simultaneously
for more than 3 seconds but less than 8 seconds and then release both. The LCD of
card(X)plore displays the PC-- marking, indicating the recorder is discoverable.]
Both recorders remain discoverable for a minute then switch back to stand by mode.
If the recorder switches back to standby mode, make it discoverable again.
After you have made the recorder discoverable, click on the Add button.
19
3. If there is a moving torch, the PC searches for Bluetooth devices. Should the recorder
switch back to stand by mode due to a timeout, make it discoverable again then click
on the Add button.
4. After the search the found devices are listed. The name of the recorder in case of
CardioBlue is HB1_xxxx, and in case of card(X)plore it is CT2_xxxx; where xxxx is
the last four digits of the serial number found on the back of the recorder. Selecting
the appropriate recorder, the OK button becomes active, please click on it.
5. As authentication key (PIN), please enter the last four digits of the serial number.
After entering the PIN, click on the Finish button.
6. Wait until the system installs and configures the new Bluetooth device.
By clicking on the Test button you can check the communication. Make the recorder
discoverable before the test as described above.
Memory cards
CardioMera and card(X)plore recorders use SD or MMC flash memory cards to record
ECG and other data during the monitoring session. Fully insert the Meditech-supplied
memory card carefully into the recorder. It is highly recommended to use a card
exclusively for ECG monitoring; using the same card for other purposes may result in
data loss, malfunction, or a failed monitoring session.
NB: All data stored on the card when inserted will be erased during programming!
You will need a card reader unit built into or connected to your computer to transfer the
recorded data to your database after a monitoring session. It is not possible to transfer
such data using the optical interface cable; the only way is to remove the card from the
recorder and insert it in a card reader unit. Use of a USB 2.0 reader is recommended.
As memory cards are not necessary during installation, registration and first startup, they
are not described in detail in this manual.
Verifying a successful installation
After successfully installing the CardioVisions software on your computer, during first
startup, you may need to register your CardioVisions installation. Registration requires
communication with a recorder (the so called key device). Therefore, if registration is
successful, it is also a verification that the system is properly installed and
communication between computer and recorder is successfully established. If you do
not register CardioVisions, log in as a normal user, and then connect and program a
recorder. If programming is successful, your system is verified to function properly.
