Abstract
A body activity sensor in a rate adaptive pacer responds to myoelectrical signals in the patient's electrocardiogram (ECG). These myoelectrical signals are a measure of body activity and thus control the pulse generation rate of the pacer. Preferably, the myoelectrical signals are obtained by filtering out high frequency portions from the ECG and processing these filtered frequency portions.
