1. A method for controlling cardiac ventricular fibrillation or other tachyarrhythmias by passing an electric current through the heart which comprises:

  • disposing a first electrode pair along the longitudinal axis of the heart;

    disposing a second electrode pair laterally between the ventricle and the region of the coronary sinus of the heart; and

    sequentially pulsing each of said electrode pairs at a voltage or voltages providing a temporal and spatial summation of delivered current above the threshold level sufficient to effect defibrillation or cardioversion of the heart.
