ECG MONITORING
Model 3000T Operation Manual

ECG MONITORING
When ECG monitoring, the ECG waveform moves across the display from left to right. The heart rate, heart rate
alarm limits, and lead selection are displayed in the upper left corner together with alarm messages. Also, a heart
symbol flashes each time a heartbeat is detected.
Safety Considerations
Disposable products are intended for single-use only. Do not attempt to re-use these products.
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.
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.
Leakage current is limited internally by this monitor to less than 10 A. However, always consider cumulative
leakage current that can be caused by other equipment used on the patient at the same time as this monitor.
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.
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.
Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias.
Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.
