ABSTRACT:
A rate-response pacemaker includes a plurality of sensors that each sense a physiologic-related parameter suggestive of the physiological needs of a patient, and hence, indicative of the pacing rate at which the rate-responsive pacemaker should provide pacing pulses on demand. The pacemaker includes appropriate selection circuitry for selecting which of the sensor parameters, or weighted combinations thereof, should be used as the sensor indicated rate (SIR) signal to control the pacing rate of the pacemaker at any given time. The pacemaker also includes a memory circuit for selectively storing the sensor parameters from each of the plurality of sensors. The stored sensor parameters may thereafter be downloaded from the pacemaker memory and evaluated in non-real time with the various sensor parameters assuming different weighting (scaling) factors and different processing parameters (e.g., filtering), thereby allowing an optimum combination of the sensor parameters to be determined without requiring repeated trials by the patient.
