An endocardial defibrillation electrode system as provided, including a coronary sinus lead, a ventricular lead, and a subcutaneous plate. The coronary sinus lead includes an elongated electrode adapted for location in the coronary sinus, extending into the great vein, and termination in the vicinity of the left atrial appendage. The right ventricular eletrode may be located either in the right ventricular apex, or may extend from the right ventricular apex to the vicinity of the tricuspid valve. This subcutaneous electrode preferably is a large surface electrode, adapted for implant in the vicinity of the heart. A variety of defibrillation pulse regimes are disclosed, optimized for use with the defibrillation electrode system, and with subgroupings of the disclosed electrodes.
