Abstract
Method and apparatus for stimulation of cells in arrhythmic myocardial tissues includes depolarizing the cells by application of a first electrical pulse or shock followed by a second electrical pulse having a polarity opposite to the first pulse. Finally, a third pulse having the same polarity as the first pulse is applied to the cells. Specific relationships between the magnitudes and durations of the pulses are advantageously employed for achieving the most desirable stimulation results.
