Asystole

Asystole is the absence of cardiac activity. The ECG will show an almost flat line and the patient will be in arrest. A common mimic of asystole occurs when an electrode accidentally falls off and the ECG suddenly flatlines – if in doubt check on the patient. If they are sitting up having breakfast, it is unlikely to be true asystole!
