Abstract

A method and apparatus for controlling a segment of excitable tissue, typically tissue of a heart, the segment having an intrinsic activity level. During a high phase, electrical energy of a given amplitude is applied to the segment. During a low phase, the amplitude of the electrical energy applied to the segment is reduced relative to that applied during the high phase, so that the segment's activity level increases during the low phase above the intrinsic activity level.
