Abstract
A cardiac pacer is provided which includes a pulse generator for providing pacing pulses and an electrical lead for connection to a chamber of the heart. A pair of separate sensing amplifiers sense selected activity of the heart chamber. One of the sensing amplifiers has a slightly lower threshold and thus a slightly higher sensitivity level than the other sensing amplifier. The thresholds of the respective sensing amplifiers are automatically adjusted so that the first sensing amplifier will sense the selected activity of the heart chamber and the other sensing amplifier will not sense the selected activity.
