Abstract
An improved automatically rate adaptive pacemaker, wherein the rate of delivered stimulus pulses is controlled as a function of sensed hearbeat characteristics and/or patient threshold. The pacemaker analyzes different characteristics or parameters of the detected heartbeat signal, and the rate of delivered stimulus pulses is controlled as a function of predetermined correlation factors. The pacemaker includes means for automatic threshold tracking, and also for adjusting the rate of delivered stimulus pulses as a continuous function of the patient threshold.
