| 1. An adaptive-rate pacing device, comprising:
an adaptive-rate sensor module;
an adaptive-rate sensor coupled to the adaptive sensor module, the adaptive-rate sensor adapted to measure an activity level
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, the monitor module adapted to monitor a plurality of maximum
intrinsic heart rates;
a calculator module coupled to the monitor module, the calculator module adapted to calculate an average maximum intrinsic
heart rate from the plurality of maximum intrinsic heart rates; and
an adjuster module coupled to the calculator module, the adjuster module adapted to adjust the adaptive-rate pacing device
using the average maximum intrinsic heart rate.
