8.3 Synchronized Cardioversion
• Using internal paddles for synchronized cardioversion requires that the patient’s ECG be acquired
through a standard ECG cable. The patient’s ECG acquired through the internal paddles may be
unreliable for synchronized cardioversion due to excessive noise or artifact causing inappropriate R-
wave detection.
• When you access synchronized cardioversion, monitoring alarms is reactivated autonomously.
8.3.1 Performing Synchronized Cardioversion
E
• During synchronized cardioversion, it is important to continue to hold the shock button (or the
paddle’s Shock buttons) until the shock is delivered. The equipment shocks with the next detected
R-wave.
8.4 Remote Synchronized Cardioversion
• During remote synchronized cardioversion, the local equipment does not display the ECG
waveform. To view the patient’s ECG, check the remote monitor.
• When you use a remote monitor as the ECG source, a biomedical technician must verify that the
remote monitor and the equipment combination will deliver a synchronized shock within 60 ms
after the peak of the next R-wave is generated.
8.5 Patient Contact Indicator
• It is recommended to perform the defibrillation on a patient when the patient contact indicator is
illuminated in green. If the patient contact indicator is illuminated in yellow, it also can be used for
the defibrillation. However, the expected effects may not be achieved in this condition.
