Abstract

An implanted system for the defibrillation of the atria of a patient's heart includes a pair of atrial defibrillation electrodes (60, 65), and a pulse generator (13) operatively associated with the first pair of atrial defibrillation elec-trodes for delivering the first atrial defibrillation pulse. The pulse generator delivers a second atrial defibrillation pulse after the first defibrillation pulse without intervening moni-toring thereof to reduce the voltage necessary for the chock, and the pain associated therewith.
