Abstract

See full text

An external defibrillator, such as a wearable defibrillator can have a heart rhythm detector to detect the heart rhythm of a patient. The defibrillator can also have a synchronous shock operating mode and an asynchronous shock operating mode. A controller can set the defibrillator in the synchronous shock operating mode or the asynchronous shock operating mode. The defibrillator can also include a shock module to cause the defibrillator to deliver shock therapy to the patient according to the operating mode of the defibrillator and a sync module configured to identify a first portion of the heart rhythm detected from a first ECG lead with which to time the delivery of the shock therapy to the patient when the operating mode of the defibrillator is in synchronous shock operating mode. A comparator module can compare timing of a QRS complex detected from the first ECG lead with the timing of the QRS complex detected by the second EGG lead.
