Abstract
A cardiac pacer includes means connected to electrodes adapted to be connected to a patient's heart for detecting and amplifying naturally occurring heart pulses. First and second counters are provided to receive periodic pulses from a clock pulse generator to time a refractory period and a stimulation pulse period, respectively. A rate limiting circuit limits the stimulation pulse rate to a predetermined rate, above which, the pacer is precluded from producing stimulation pulses. A test circuit is selectively connectable to produce a visual indication of the production of a stimulation pulse.
