ABSTRACT:
A heart stimulator, with verification of capture in the atrium of a heart, contains an atrial pulse generator which, via an atrial electrode, emits stimulation pulses in the atrium and a ventricular detector which senses depolarization signals in the ventricle via a ventricular electrode. The time which elapses between two consecutive stimulation pulses emitted in the atrium can be varied, and variation in ventricular events associated with the stimulation pulses is studied. If the ventricular events vary in time in the same way stimulation pulses emitted in the atrium vary, AV conduction is functional, and capture is present in the atrium.
