Synchronized Cardioversion Functional Check
This section describes how to check the synchronized cardioversion function.
1. Set up the simulator and the analyzer.
a. Connect the ECG simulator to the ECG cable. Connect the defibrilla-
tor analyzer to the pads cable.
b. Set the simulator for normal sinus rhythm (NSR), 1mV amplitude, at
some nominal rate (e.g., 60 bpm).
2. Set up the M4735A.
Set the defibrillator to Manual Mode, and press (Sync On/Off).
3. Check Cardioversion.
a. Verify that sync markers appear on the display, at the peak or on the
falling side of the QRS complex. Adjust the size of the displayed
ECG as needed to view it more clearly.
b. Select an energy of 5 J. Press then press and hold
until the shock is delivered (at next QRS).
c. Verify on the defibrillator analyzer that the shock was delivered, and
was 5J ±2J.
d. If the unit is configured to do so, verify that it prints a strip with the
correct information on it (waveform, text).
e. Verify on the defibrillator analyzer that the delay between the peak of
the QRS and the delivered shock was <
60 msec.
