  • Rate adaptive pacemaker with adjustment of sensor rate as a function of sensed sinus rate
    Patent number: 5350409
    Abstract: A rate adaptive pacemaker and method of operation, where the sensor-indicated rate is adjusted as a function of sensed sinus rate. The pacemaker is particularly adapted for VDDR operation. The natural sinus rate is compared to the sensor-indicated rate at one or more rates, and the sensor response function is adjusted, or adapted as a function of such comparisons, so as to optimize sensing of the atrial rate and maintenance of synchronous operation. The rate response function may be adjusted specifically at upper pacing limit, and may also be adjusted as a function of comparisons made at other rates.
