Abstract
Method and apparatus for transcutaneously pacing the heart using two or more pairs of electrodes to reduce patient discomfort during pacing. The pacing stimuli are divided into two or more series of pulses, with at least one series of pulses being delivered by an electrode pair that differs from an electrode pair delivering another series of pulses. Typically, the electrode pairs are arranged so that current paths between electrodes in each pair of electrodes intersect at the patient'"'"'s heart.
