Heart stimulator
First Claim
Patent Images
1. A heart stimulator comprising:
- pulse generator means for generating and emitting stimulation pulses to a heart at a rate;
detector means for sensing events in said heart, including spontaneous heartbeats; and
control means, connected to said pulse generator means and to said detector means, for controlling the emission of stimulation pulses by said pulse generator means for causing the emission of a stimulation pulse if a spontaneous heartbeat rate as sensed by said detector means drops below a defined basic rate and for causing said pulse generator means, when said spontaneous heartbeat rate falls below said defined basic rate, to emit said stimulation pulses at a rate faster than said defined basic rate and for subsequently slowing the rate of emission of said stimulation pulses down to said defined basic rate.

Abstract
In a heart stimulator which delivers stimulation pulses to a heart when the heart'"'"'s spontaneous rate drops below a defined basic rate, in order to reduce the period during which the heart stimulator emits stimulation pulses, the defined basic rate is slow. When the spontaneous heart rate drops below the defined basic rate, stimulation pulses are initially emitted at a faster stimulation rate, in relation to the basic rate, the stimulation rate then dropping toward the defined basic rate.
