Abstract

An apparatus and method for delivering defibrillation shock therapy employing a multi-terminal pulse output circuit. In such a circuit, at least three electrode lead terminals are switchably connected to the positive and negative terminals of an energy storage capacitor. By serially switching selected electrode lead terminals to the capacitor terminals, a variety of shock pulse waveforms may be generated.
