Abstract
An implantable cardiac rhythm management device includes a controller adapted to receive digitized electrocardiogram signals from leads placed on or in the heart. The device also incorporates an autosense algorithm which automatically adjusts the sensing threshold dependent upon an average or maximum amplitude of noise detected during a period following a sensed cardiac depolarization. The sensing threshold is automatically set on a beat-to-beat basis at a level such that the signal to noise ratio exceeds a preset value.
