A semiautomatic defibrillator with the capability of delivering a synchronized shock. An advisory algorithm automatically determines whether a synchronized shock should be delivered (e.g., because a shockable tachycardia is detected) and what ECG event should trigger delivery of the shock. And following initiation of a shock by the operator, the defibrillator automatically waits until the required ECG event is detected to deliver the shock. This happens automatically, without the operator being asked to decide between a synchronized and unsynchronized shock, or having to do anything differently to deliver a synchronized shock (e.g., without having to hold a button depressed as necessary to deliver a synchronized shock in manual defibrillators). The unit delivers a shock at the end of a predetermined period if the required ECG event has not been detected, so that a shock always results when the operator initiates one.
