Abstract

A system and method for synchronizing delivery of shock therapy to a patient from a defibrillator. The period for a patient ECG waveform exhibiting a threshold periodicity is calculated and a time reference during the period of the ECG waveform is determined for delivery of shock therapy to the patient. The defibrillator is prepared for delivery of the shock therapy at the time reference during a subsequent period of the ECG waveform.
