Abstract
A cardiac pacing system and method provides rate control as a function of sensed myocardial contractility. A signal representative of short term, e.g. cycle-to-cycle, heart contractility is derived from a sensor which measures intramyocardial pressure. A microprocessor-band controller provides logic and memory capacity for carrying out a signal processing algorithm for determining and selecting optimum pacing rate as a function of sensed intensity of the active state of the cardiac muscle.
