Special Notice to User

Malfunction caused by EMC

The Cardimax FX-7302 complies with the safety standards IEC60601-2-25 (1999) and

IEC60601-1-2 (2001). However, if there is a strong electromagnetic wave nearby that exceeds the prescribed limit, the device could malfunction. If this happens, provide the required countermeasures.

Influence of radiation electromagnetic wave:

The use of a cellular phone could affect the operation of FX-7302. Alert persons in a facility where medical electronic equipment is installed to turn off their cellular phones and small radio equipment.

Influence of bursts and conduction electromagnetic wave:

High-frequency noise from other equipment may infiltrate into FX-7302 through the AC outlet. Identify the noise source and stop use of the relevant equipment if possible. If this equipment cannot be shut down, provide the countermeasures for this noise route using a noise suppressing device, etc.

Influence of static electricity:

The discharge of static electricity could affect the operation of FX-7302 in a dry environment (room), particularly in winter. Before using FX-7302, humidify the room or discharge static electricity from a patient and person who will record the ECG.

Influence of surge (lightening):

If there is a thunderstorm occurring nearby, it might cause a voltage surge in FX-7302.

If you expect any danger, unplug the power supply cord from the AC outlet and run FX-

7302 on built-in battery power (optional). Also use an uninterruptible power supply, if you have one.

Equipment classification

The Cardimax FX-7302 falls under the following equipment classifications:

PC-7303,

PC-7304

Precautions on analysis program

CAUTION

Interpretation and Minnesota codes given by the Cardimax FX-7302 do not instruct the physician as to the kind and degree of cardiac disease. Accordingly, four value judgments are given for electrocardiogram (ECG) waveform and although "abnormal" indicates a large possibility of organic cardiac disease, there are cases where no cardiac disease exists despite an abnormal ECG (that is, an abnormal ECG may be caused by something other than the heart). On the other hand, care should be taken in the event any preclinical coronary arteriosclerosis could be present despite a normal ECG interpretation. Therefore, for a proper diagnosis, the ECG should be integrated with other interpretations. This program is not an arrhythmia monitor.

The FX-7302 has no arrhythmia alarms. iv

Precautions on measurement program

CAUTION

The equipment may measure the ECG waveform incorrectly due to external noise

(such as a drift of baseline, electromyogram, AC interference, etc.). Another matter which requires careful consideration is that tiny R waves in V1 and V2 may be overlooked and the S wave could be interpreted as Q wave.

Precautions on battery pack

DANGER

• Be sure to use the specified battery pack (T8HR4/3FAUC-

5345).

• Be sure to charge the battery using the Cardimax FX-7302.

Charging the battery using other equipment could lead to a hazard.

• Do not disassemble or mutilate the battery. You could burn yourself.

• Do not incinerate or heat the battery. You could burn yourself, or the battery could burst or leak toxic substances.

• Do not short the battery. You could burn yourself.

• Keep away from children.

• If the liquid contained in the battery gets into your eyes, do not rub them. Wash your eyes thoroughly with water and see a doctor immediately.

Nonexplosion proof

DANGER

Do not operate the FX-7302 in an environment where there is a risk of explosion. Do not operate the FX-7302 in the presence of flammable anesthetics.

Magnetic resonance imaging

WARNING

Do not operate the FX-7302 during Magnetic Resonance Imaging

(MRI) scanning. The conducting current may cause burns.

Operating the FX-7302 may affect the MRI image, while the MRI may affect the accuracy of the FX-7302. v

High-frequency surgery

WARNING

The patient cable (CP-104T, CP-104L or CP-104J) contains resistors installed in the lead wire plugs to prevent damage to the equipment when used in the presence of high frequency surgery apparatus. These components reduce the risk of not only device damage, but also the risk of burns to the patient.

Defibrillation protection

WARNING

The FX-7302 may remain connected to the patient during defibrillation only if the proper patient cable provided with defibrillator protection is being used. The patient cable (CP-

104T, CP-104L or CP-104J) is provided with defibrillation protection. The FX-7302 will not be damaged when these cables are used, even if the defibrillator paddles come into contact with the ECG electrodes.

Connection

DANGER

• This isolation measure is provided to protect the patient.

Operation is bypassed if the electrodes on the patient cable come into contact with any other metal object or other electrically conductive objects, including the operator’s hands.

When such contacts occur, there is a risk of electric shock, regardless of whether or not the objects are grounded.

• All ECG wires (patient connections), connectors, and amplifiers are electronically isolated from the rest of the device and from ground. This isolation restricts the current that can pass through a patient to less than 10 microamperes.

• If the power supply cords of several different units are connected together in a multiple outlet touch, an increase in chassis leakage current can create a potential hazard.

• When a cardiac pacemaker or other electrical stimulator is connected to the patient, it increases the risk of a potential hazard. Pay particular attention to safety measures to record

ECG in such conditions. Appropriate measures must be taken to assure that the chassis leakage current is at a safe level.

• The FX-7302 is a Type CF equipment. It must not, however, be placed in direct contact with the area of the heart.

Be sure to connect the power supply cord to a hospital-grade wall

AC outlet. If no hospital-grade wall outlet is available, connect the potential equalization cable securely to a proper ground. If no proper grounding is available, operate the FX-7302 on its rechargeable battery. vi

Preventive maintenance

CAUTION

The purpose of preventive maintenance is to assure that the device is always in a safe operating condition and to prevent possible future problems. Preventive maintenance should be performed at least once during each 12-month period.

Preventive maintenance consists of a thorough inspection of the device, all connections, and all attached cables for signs of physical damage. Immediate maintenance must be performed if:

• The device was subject to extreme mechanical stress; e.g., after a heavy fall.

• Liquid or fluids have spilled on or into the device.

• The device does not function, or functions improperly.

• Parts of the device cabinet are cracked, broken, or damaged.

• The power supply cord or the patient cable and interconnecting cables show signs of deterioration.

• Do not subject the liquid crystal display to a strong impact.

The device can be damaged by unwarranted force.

• Make sure that a patient does not come in contact with FX-

7302, other electric appliances, or metal.

Such contact increases the leakage current and can become a source of danger to a patient.

• Do not insert a CF card in the wrong direction or with too

much force.

This could cause damage to both FX-7302 and CF card.

• When you unplug a cord, be sure to hold the plug to remove the cord (do not pull the cord itself). Also, do not plug/unplug the cord with wet hands.

This could cause an electric shock, short circuit, or injury.

• Operate the touch-panel display with a finger.

If you touch the touch-panel screen with a tool instead of your finger, this could damage the surface of the touch-panel screen and cause the device to malfunction.

• Wipe off dirt on the surface of the touch-panel display with a soft cloth moistened using ethanol or with the silicon cloth supplied with the accessories.

• When not using the FX-7302, keep it covered using the equipment cover supplied with the accessories to prevent liquid spilling into the liquid crystal display.

Checks：

• Perform the daily checks to assure the safety of FX-7302.

Preparing the Cardimax FX-7302

This chapter will help you to choose an installation site, configure, and set-up the Cardimax FX-7302. Follow the instructions provided here to ensure that your electrocardiograph installation process is smooth and trouble-free. Be sure to provide a ground connection using the optional potential equalization cable (CE-12) if the FX-7302 is installed in a place where there are no hospital-grade 3-pin wall outlets.

Site selection

The FX-7302 has been designed so that in addition to using it in hospitals and clinics, you can easily carry and battery-operate it anywhere, for field activities such as a group examination. As you decide where you want to locate the Cardimax FX-7302, take the following matters into consideration to get accurate ECG recordings:

• Keep the Cardimax FX-7302 and the patient's bed away from high-tension wires or high-voltage power lines. If there is an intense radiation source near the Cardiax

FX-7302, the ECG will absorb noise interference.

• Do not install the Cardimax FX-7302 near X-ray units, ultrasonic equipment, radios, and fluorescent lamps. They could easily become sources of trouble.

• Use the Cardimax FX-7302 in an environment where the room temperature is maintained at 10 to 40 degrees Celsius (50 to 104 degrees Fahrenheit).

• Use the Cardimax FX-7302 in an environment where the relative humidity is from 10 to 95 percent (non-condensing).

• Install the Cardimax FX-7302 in a place where a hospital-grade 3-pin wall outlet is available or a site that provides a secure ground connection.

Chapter 3

Attaching Electrodes to the Patient

Follow the instructions below to attach electrodes to a patient. Placing the electrodes in their proper locations is one of the most important factors for accurate ECG recording. Much care must be taken to ensure good electrical contact.

Before attaching the electrodes to a patient

Check the condition of the patient

Check the condition of the patient and make sure the person is resting quietly and comfortably. If the patient is tense, relieve tension by talking to the patient. For example, ask them to "Relax your arms and legs and feel completely at ease" or

"Breath normally". You cannot record an accurate ECG if the arms and legs of the patient are tense or the patient keeps moving about, because of problems such as electromyogram interference and unstable baseline.

Cleaning the skin

Use an alcohol-moistened cloth and wipe parts of the patient's body where the electrodes are going to be attached, to remove dirt and fatty oil. If foreign substances such as dust remain on the skin or an electrode, the contact resistance will increase and the recording will become unstable.

Applying Keratin cream

Apply Keratin cream for better contact between the skin and electrode. Rub the cream into the patient's skin until the skin becomes slightly reddish. When applying the cream to different parts of the chest to attach electrodes, make sure that the cream on these different parts does not overlap or touch. If adjacent electrode locations on the chest become linked through Keratin cream applied too generously, an accurate ECG will not be recorded.

Attaching the limb electrodes (4 locations)

Clamp the arms and legs (several centimeters above the wrist and ankle) firmly with the electrode clips. Make sure the patient does not experience pain or discomfort.

44

Operating the Cardimax FX-7302: Recording a Standard 12-lead ECG in the Automatic Recording Mode

Attaching the chest electrodes (6 locations)

Attach the chest electrodes in the following locations: Make sure the patient does not feel pain or discomfort.

① : The fourth intercostal space on the right sternal border.

② : The fourth intercostal space on the left sternal border.

③ : Midway between locations ② and ④ .

④ : The fifth intercostal space on the left mid-clavicular line.

Chapter 7.5 Stress Test

This chapter describes the series of operations required to perform the stress test.

Precautions

• Use the AC power source.

Do not use the battery as the power source for running the stress test.

• Before starting the stress test, make sure to load enough recording paper.

• Filters

In the Stress Test Mode, the filters are set in accordance with the "HUM FILTER",

"MUSCLE FILTER", and "DRIFT FILTER" parameters in the STRESS TEST SETUP screen.

• On the [1mV] key

The [1mV] key is disabled during the Stress Test Mode. Even if this key is pressed, the calibrated 1mV waveform will not be recorded.

• Check the ergometrics er800/er900/variobike 550/variotrainer 500 connection beforehand.

Otherwise, the message "ERGOMETER ERROR" will appear when the ergometrics er800/er900/variobike 550/variotrainer 500 is initialized after starting the Stress Test

Mode.

• Perform sufficient warming up and cooling down.

Overview of the Stress Test

This section gives an overview of the entire stress test procedure. Before actually starting the stress test, read the information below to become familiar with entire sequence of operation. These activities are fully described in the subsequent sections of this chapter.

The activities to be performed are mainly divided into 5 phases:

Phase 1: Preparation Phase ________________________________________

Phase 1

Phase 2 Phase 3 Phase 4 Phase 5

• Prepare the FX-7302 and ergometer.

• Attach the electrodes to the patient.

• Enter the Stress Test Mode.

• Enter the patient data including the target heart rate used for the stress test.

• Check the display and print out the resting 12-lead ECG to examine the condition of the patient to find out whether he/she is well enough to perform the exercise (stress test).

128

• Print out the wave report manually if required. (The intermittent reports are also printed out automatically when this is programmed using the STRESS TEST SETUP screen.)

• When you perform the exercise test with the ergometer, set up the loading dose(W) manually if needed.

Phase 4: Recovery Phase __________________________________________

Phase 1 Phase 2 Phase 3

Phase 4

Phase 5

• When the patient's heart rate reaches the target heart rate or if any symptom which calls for stopping the exercise is detected, set the end point for stopping the exercise.

When the cooling down load and time are programmed for the selected protocol, the

Recovery Phase starts automatically.

• Monitor the patient and ECG during cooling down.

• Monitor the patient and post ECG until the heart rate of the patient returns to what it was during the resting status.

• Print out the intermittent report manually if required. (The intermittent reports are also printed out automatically when this is programmed using the STRESS TEST

SETUP screen.)

Phase 5: Final Report Recording Phase _______________________________

Phase 1 Phase 2 Phase 3 Phase 4

Running the Stress Test

Follow the step number to perform the stress test.

Phase 1: Preparation Phase

Phase 2: Pre-test Phase

Phase 3: Exercise Phase

Phase 4: Recovery Phase

Phase 5: Final Report Recording Phase

1 Turn ON the Power ______________________________________________

Check whether all equipment is connected properly.

Turn on the MAIN POWER switch on the FX-7302. Turn on the main power switch of the ergometer.

Note:

Use the AC power source. Do not use the battery as the power source for running the stress test.

See the relevant manuals for details about the power on sequence.

2 Attach the Electrodes to the Patient _________________________________

Follow the instructions below to attach the electrodes to the patient. Electrode placement is one of the most important factors for accurate ECG recording. Sufficient care must be taken to ensure good electrical contact.

Before attaching the electrodes to the patient

(1) Check the conditions of the patient

Check the conditions of the patient and make him/her rest quietly. If the patient is tense, relieve the tension by talking to the patient.

Phase 1 Phase 2 Phase 3 Phase 4 Phase 5

Preparation Phase 130

Stress Test Mode

(2) Clean the skin

Wipe the parts of a patient's body to which the electrodes are going to be attached with an alcohol-dampened cloth to remove dirt and fatty oil. If foreign substances such as dust remain on the skin or an electrode, the contact resistance will increase and the recording will become unstable.

Attach the electrodes to the patient

(1) Attach the R, L, F, and N limb/extremity electrodes.

(2) Attach the C1, C2, C3, C4, C5, and C6 chest electrodes.

Make sure the patient does not feel pain or discomfort.

The following figure shows the most typical electrode placement (Mason-

Likar 12-lead system) in a stress test.

Chapter 7

Note:

ECG recording by the Mason-Likar system

The 12-lead ECG recorded with the torso placement of the limb leads (Mason-Likar 12lead system) may differ from the standard 12-lead ECG. Moreover, waveforms may differ somewhat also in a supine position and a standing position (sitting position).

We recommend to carry out the recording of the ECG by taking into consideration the waveform differences according to electrode positions or postures.

Electrode Placement

To reduce the waveform differences from the standard 12-lead, we recommend that the torso placement of the R and L electrodes be near as possible to each arm, in the infraclavicular fossae, within the area unaffected by myoelectricity.

For the model installed with ECG interpretation program

The ECG interpretation program is intended to analyze the standard 12-lead ECG waveforms. Therefore, the analyzed result for waveforms recorded with the torso placement of the limb leads (Mason-Likar 12-lead system) may differ from that of the standard 12-lead ECG waveforms.

3 Connect the Patient Cable ________________________________________

Connect the following optional patient cable.

Optional patient cable: CI-100HL/CI-100HT

There are two special patient cable: CI-100HL for U.S. and CI-100HT for Europe.

Note:

The CI-100HT comply with European Community(CE) requirements.

If you use this patient cable, contact your local Fukuda Denshi sales and service representative.

2. ECG Data

The following provides an explanation of the ECG data sent as a reply from the FX-7302 to the PC.

Data can be output in either Fukuda Original format or SCP-ECG (Standard Communications Protocol for

Computer-Assisted Electrocardiography) format. Use Set Up mode to select the format.

Data in Fukuda Original format can only be viewed on a PC with EFS-200 installed. The SCP-ECG format is compliant with the IEC 62D/443/NP protocol (proposed on August 17, 2001).

An explanation of the SCP-ECG format output by the FX-7302 is given below.

Glossary

Backup battery:

A NiMH battery used for retaining clock data. For replacement, contact your local

Fukuda Denshi service representative.

Coefficient of variation (CV):

The R-R Trend Test Mode measures the R-R interval of the sampled ECG waveform and calculates the coefficient of variation using the following formula:

Coefficient of variation (CV) =

Standard deviation

Average RR

×

100%

Dominant waveform:

Removes beats suspected to be a premature beat, beats with baseline disturbance, and noise used for measuring each waveform (P wave, R wave, etc.) among the ECG waveforms sampled for 12-lead analysis, picks the best beat as a typical waveform.

This is called a dominant waveform.

The Dominant waveform is used to calculate the following parameters in Analysis and

Measurement Recording:

P-R, QRS, QTc, AXIS, RV5(6), SV1, and R+S.

For a complete discussion of waveform parameters, see the supplied "Program Guide

Book" (PI-13).

Electrical axis:

The FX-7302 calculates the electrical axis of the QRS complex using the following formula:

Electrical axis ( ° ) =

√

3 ( + )

2

× Ι + Ι Ι - Ι Ι Ι

Filter:

Noise such as AC interference (50/60Hz), electromyogram (25Hz or more), and drift

(0.5Hz or less) may become mixed with the ECG signal. The filter can eliminate such noise. The FX-7302 performs digital processing using a microcomputer. Note, however, when the muscle filter is used, the amplitude of the QRS complex could be reduced.

Heart rate indication:

The FX-7302 displays the heart rate on the screen. The lead specified for the

RHYTHM LEAD 1 parameter (SET UP MODE (STANDARD ECG MODE)) is used and the average of 4 beats are calculated. This value is displayed as the heart rate.

Histogram:

Displayed on the R-R trend test result report. The measured R-R interval is indicated on the horizontal axis and its frequency is indicated as a percentage on the vertical axis.

231

Glossary

A histogram picks up only the normal beat from all the R-R intervals measured, and represents these normal beats in a graph.

Minnesota code:

The Minnesota code was developed by the University of Minnesota in the U.S., and is designed so the 12-lead ECGs can be classified objectively by a common standard.

For details about the Minnesota code, see the supplied "Program Guide Book" (PI-18).

Standard deviation (SD):

The R-R Trend Test Mode measures the R-R interval of the sampled ECG waveform and calculates the standard deviation using the following formula:

Standard deviation (SD) =

N

Σ n = 1

2

(RRn - Average RR)

N

Transitional zone:

Normally, the R wave gradually becomes larger from the V1 lead to V6 lead, and the S wave gradually becomes shallow. The lead portion where the R wave and S wave are nearly equal is called the transitional zone.

Trend graph:

Displayed on the R-R trend test result report. The elapsed time is indicated on the horizontal axis and the measured R-R interval is indicated on the vertical axis.

A trend graph represents all R-R intervals measured in a graph.
