Cardiac defibrillator including an electronic energy transfer circuit

DETAILED DESCRIPTION The invention pertains to an energy transfer circuit for delivering a cardiac defibrillation pulse to a patient.
The energy transfer circuit comprises an energy storage capacitor for storing an electric charge before the defibrillation pulse is delivered to the patient and electronic switch means coupled to the storage capacitor for controlling the delivery of a defibrillation pulse to a pair of electrodes disposed on the patient.
A controller means is provided to control the electronic switch means.
Current shunt means coupled to the electronic switch means diverts a leakage current flowing through the electronic switch means away from the pair of electrodes until the electronic switch means begins the delivery of the cardiac defibrillation pulse to the patient.
