The cardiac pacer disclosed herein employs a digital counter driven by a relatively high frequency oscillator to time intervals which simulate various cardiac functions. When allowed to cycle repetitively, the counter provides a relatively slow, fixed rate mode of operation. However, the counter may be reset under certain conditions by ventricular signals to provide a demand mode of operation and by atrial signals under certain other conditions to provide a so-called synchronized mode of operation. Noise rejection circuitry is also disclosed.
