ECG Acquisition via Separate ECG Electrodes
Use only silver/silver-chloride electrodes to
acquire the ECG signal. These electrodes prevent
polarization voltages which may be caused by the
defibrillation shock, resulting in an ECG trace on
the monitor screen or recording that simulates
cardiac arrest. The ECG can be picked up with 5
or with 10 electrodes (for ECG measurement,
however, 10 ECG electrodes are required (chapter
8)).
•
Apply the electrodes as shown in Figure 5-6.
•
Ensure that only those leadwires are connected
to the patient cable that are actually required.
•
Via the patient cable, connect the electrodes to
the defibrillator.

Turn on the device (energy selector to
On the monitor screen you will now see the 3 ECG
leads selected in the setup menu (factory defaults:
leads I, II, III, Figure 5-7). The analysis algorithm
always uses ECG lead II. If lead II is not available,
the first suitable ECG lead shown will be selected.
Follow these steps to change the displayed leads or
