Abstract (en)
In a demand pacer, an input amplifier (1) senses stimulating pulses and natural heart beat signals, and responsively thereto establishes control of a subsequent stimulating pulse. Charge accumulation on an output capacitor (8) governs recovery time after each generated stimulating pulse. Respective first (10) and second (12) flip-flops, responsive to the input amplifier and the demand pacing logic, establishes a reduced recovery time, after each generated pulse, wherein charge accumulated on the output capacitor is dissipated.
