ABSTRACT:
A cardiac pacing apparatus includes a trigger pulse generator which generates trigger pulses at a predetermined minimum rate when the natural heart rate fails to exceed the predetermined minimum rate and which follows the natural heart rate when the heart rate is above the predetermined rate, an output pulse generator for generating artificial heart stimulating pulses, a timing interval generator for generating a fixed timing interval in response to the generation of each artificial heart stimulating pulse, and an inhibit gate for selectively applying only those trigger pulses which occur outside the fixed timing intervals to the output pulse generator. The output pulse generator is maximum-rate limited as an inverse function of the fixed timing interval duration regardless of the input rate, and pulses at the minimum predetermined rate, as established by the trigger pulse generator, are generated after an escapement interval in the absence of natural cardiac activity. The trigger pulse generator may be a triggerable astable multivibrator and the timing interval generator may be a nonretriggerable monostable multivibrator.
