Abstract
An energy delivery system for use with an automatic external defibrillator (AED), the AED having a case containing a plurality of AED components, a battery electrically coupled to a control system, the control system communicatively coupled to a charge system, the charge system for generating a stored quantity of energy responsive to a communication from the control system, the control system selectively commanding a discharge of the stored energy to an electrical connector, the energy delivery system includes three electrodes, each electrode for making electrical contact with a skin surface of a patient, each electrode being in electrical contact with the electrical connector for communicating the stored energy to the patient. A method of defibrillating the heart of a patient using an AED, the AED having electrical energy discharge circuitry for generating a defibrillating energy discharge to affect the heart of the patient, the heart being in a state of fibrillation, includes the steps of placing three electrodes on the person of a patient to define a desired electrical path and discharging electrical energy across the electrical path.
