Sequential-pulse, multiple pathway defibrillation method
First Claim
1. A method for controlling ventricular fibrillation or tachycardia comprising the steps of locating a first electrode adjacent the right ventricle, locating a second electrode adjacent at least one of the superior vena cava and inferior vena cava, locating a third electrode at the chest wall and sequentially pairing and pulsing two of said electrodes with the remaining electrode.

Abstract
A method of controlling cardiac ventricular fibrillation and other tachyarrhythmias. A catheter carrying a first and second electrode is located in the right ventricle such that the first electrode is located in the right ventricle and the second electrode is located in the superior vena cava. A third electrode is located either at the chest wall or at the abdominal cavity. The third electrode can be implanted subcutaneously in the left chest wall. It can also be located in the abdomen immediately beneath the diaphragm. It could also be implanted in the epigastric area overlying the superficial abdominal muscles and underneath the skin and fat. The second and third electrodes are sequentially paired and pulsed with the first electrode to control ventricular fibrillation and other tachyarrhythmias.
