Monitoring ECG
6.1 Overview
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it as waveforms and numerics. The
equipment enables ECG monitoring through 3-, 5- lead ECG sets, external paddles and multifunction electrode pads. If
both ECG sets and paddles/pads are connected, the configured ECG waveforms are displayed in the waveform area.
6.2 Safety
WARNING
z
Periodically inspect the electrode application site to ensure skin quality. If the skin quality changes, replace
the electrodes or change the application site.
z
Use defibrillation-proof ECG cables during defibrillation.
z
When monitoring a patient implanted with a pacemaker, be sure to select correct paced status. Otherwise,
the pacing pulses may be counted in the case of cardiac arrest or some arrhythmias. Do not completely rely
on the heart rate reading or the heart rate alarms. Always keep paced patients under close surveillance.
NOTE
z
When connecting electrodes and/or patient cables, make sure that the connectors never come into contact
with other conductive parts, or with earth. Particularly make sure that all of the ECG electrodes are attached
to the patient.
z
Interference from a non-grounded instrument near the patient and electrosurgery interference may cause
problems with the waveform.
z
If selected lead cannot provide valid ECG signals, a dash line is shown in the ECG waveform area.
z
Avoid using external paddles for ECG monitoring if possible.
z
Use the same type of ECG electrodes when monitoring ECG through ECG lead set.
