Patent ID: 7050854

Claim:
An adaptive-rate pacing device, comprising: an adaptive-rate sensor module adapted to be coupled to a heart of an individual and an adaptive-rate sensor, wherein the adaptive-rate sensor is programmed to measure an activity level of the individual and communicate a signal proportional to the activity level to the adaptive-rate sensor module; a monitor module coupled to the adaptive-rate sensor module, wherein the monitor module is programmed to monitor a plurality of daily maximum intrinsic heart rates; a calculator module coupled to the monitor module, wherein the calculator module is programmed to calculates an average maximum intrinsic heart rate from the plurality of daily intrinsic maximum heart rates and compares the average maximum intrinsic heart rate to a maximum sensor rate of the adaptive-rate pacing device; and an adjuster module coupled to the calculator module, wherein the adjuster module is programmed to increases the maximum sensor rate if the average maximum intrinsic heart rate is greater than the maximum sensor rate.
