Abstract
An electrotherapy circuit administers to a patient a current waveform. The electrotherapy circuit includes a charge storage device, at least two discharge electrodes connected by electrical circuitry to opposite poles of the charge storage device, and a control circuit. The control circuit is connected to the charge storage device and controls a continuous discharge of the charge storage device through the electrodes so as to produce at least one phase of a current waveform that includes a sawtooth ripple with a height less than about one-quarter of the average height of the phase.
