Abstract
An implantable defibrillation/cardioversion system and method comprising an electrode having a plurality of discrete electrically conductive segments. The conductive segments are electrically isolated from each other and electrically connected to a defibrillation/cardioversion unit. An electrical pulse block is generated and chopped into a plurality of discrete pulse segments by the defibrillation/cardioversion unit and applied to the electrode so that each conductive segment receives a particular electrical pulse assigned from the series of pulses. In this way, the concentration of gas generated from ionic current produced by a high energy defibrillation pulse is reduces and more energy is delivered to the heart, thus reducing the required energy input to the electrode. The electrode may be planar or in a catheter electrode configuration.
