Abstract
Methods of adjusting output mapping in response to historical signal input data relative to a reference value, and apparatus to perform the methods. The methods are suited for use in adjusting rate-adaptive pacemakers in response to a patient's demonstrated activity relative to a predetermined activity level. The methods include using historical physiologic sensor input to derive a patient's activity. The methods further include tuning a rate-adaptive curve in response to a demonstrated exertion level and a demonstrated exertion time indicative of a breadth and frequency of a patient's activity above some reference value. Pacemakers adapted to perform the methods include a processor, at least one physiologic sensor, a variable-rate pulse generator and a memory for storing historical physiologic sensor data.
