Demand pacer having reduced recovery time

摘要

In a demand pacer, an input amplifier senses stimulating pulses and natural heart beat signals, and responsively thereto establishes control of a subsequent stimulating pulse. Charge accumulation on an output capacitor governs recovery time after each generated stimulating pulse. Respective first and second 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.
