<p>An improved automatically rate adaptive pacemaker, wherein the rate of delivered stimulus pulses is controlled as a function of sensed heartbeat characteristics and/or patient threshold. The pacemaker analyzes different characteristics or parameters of the detected heartbeat signal (82-89), and the rate of delivered stimulus pulses is controlled as a function of predetermined correlation factors. The pacemaker includes means (101, 102) for automatic threshold tracking, and also for adjusting the rate of delivered stimulus pulses as a continuous function of the patient threshold (95, 60, 59).</p> |
