Abstract

External pacemaker systems and methods deliver pacing waveforms that minimize hydrolysis of the electrode gel. Compensating pulses (161, 163, 165) are interleaved with the pacing pulses (150, 152, 154), with a polarity and duration that balance the net charge at the electrode locations. The compensating pulses (161, 163, 165) are preferably rectangular for continuous pacing, and decay individually for on-demand pacing.
