Apparatus for automatically controlling the delivery of excitable tissue control signals to a heart. The apparatus includes an excitable tissue control unit for delivering excitable tissue control signals to the heart, an action potential duration (APD) determining unit for receiving sensed cardiac action potential related signals. The APD determining unit determines an estimated action potential duration value from one or more action potential related signals, computes one or more excitable tissue control signal parameters, and controls the delivery of excitable tissue control signals based on the computed signal parameter(s). The cardiac action potential related signals may be cardiac close bipolar electrogram signals and cardiac monophasic action potential signals. Methods are disclosed for use with the apparatus to control the delivery of excitable tissue control signals to the heart.
