Abstract:
A heart stimulator arrangement (100), havinga stimulation pulse generator (102) and output means (103B, E.sub.V) connected to it for outputting stimulation pulses to the ventricle (V) of a heart (H),a heart signal input stage (101) for detecting evoked heart signals, in particular the ventricular evoked response VER,an AV delay unit (103A), connected on the output side to the stimulation pulse generator, for generating an AV interval (.DELTA.AV) between an atrial cardiac event or atrial stimulation pulse and a stimulation pulse output to the ventricle,an AV interval calculator (100B), connected on the input side to the heart signal input stage and on the output side to the AV delay unit, for calculating the AV interval on the basis of at least one parameter of the heart signal,characterized in thatthe heart signal input stage is embodied for detecting the signal shape of evoked heart signals, in particular the morphology of the ventricular evoked response (VER), and the AV interval calculator is embodied for calculating the AV interval on the basis of the heart signal shape detected.
