ECG MONITORING
Model 7600/7800 Operation Manual
9.0 ECG MONITORING
Dual simultaneous ECG waveforms move across the display from left to right. The top waveform (Trigger) is used
for cardiac triggering. The bottom trace (Second) is used for display only. Lead selections are displayed to the right
of their respective waveforms. The heart rate and heart rate alarm limits are displayed on the upper part of the
screen. Alarm indications appear on the center of the screen and flash once per second. Also, a heart symbol flashes
each time a heartbeat is detected.
9.1 Safety Considerations
WARNING: This monitor is supplied with protected lead wires. Do not use cables and leads with
unprotected lead wires having exposed conductors at the cable end. Unprotected lead wires and cables may pose an
unreasonable risk of adverse health consequences or death.
CAUTION: ECG Electrodes are intended for single-use only. Do not attempt to reuse.
CAUTION: ECG Patient connections are electrically isolated Type CF For ECG connections use
insulated probes. Don’t let patient connections contact other conductive parts, including earth. See instructions for
patient connections in this manual.
CAUTION: Leakage current is limited internally by this monitor to less than 10 μA. However, always
consider cumulative leakage current that can be caused by other equipment used on the patient at the same time as
this monitor.
CAUTION:
The Model 7600/7800 is compatible with HF electrosurgical devices. When used with HF
electrosurgical devices, applied parts of the equipment are provided with protection against burning of the patient.
To avoid the potential of electrosurgery burns at ECG monitoring sites, ensure proper connection of the
electrosurgery return circuit as described by manufacturer’s instructions. If improperly connected, some
electrosurgery units might allow energy to return through the electrodes.
CAUTION: Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart
rate alarms. To minimize this problem, ensure proper electrode placement and cable arrangement.
