A system, apparatus, and method of delivering a defibrillation pulse to the heart of a patient generally includes positioning a pair of electrodes on the exterior surface of the patient's body such that at least one of the electrodes is placed on a limb, e.g., arm or leg, of the patient in a position proximate to the patient's torso. An electrical defibrillation pulse is then delivered through the electrodes, into the limb, enabling the electrical defibrillation pulse to travel from the limb to the heart of the patient.
