Abstract

L'invention concerne un stimulateur cardiaque comportant un circuit de vérification de capture. Ce circuit de vérification de capture comporte un circuit qui détecte si le coeur a réagi à une impulsion de stimulation, avec un circuit de fixation de niveau et de compensation de tension qui élimine les charges résiduelles dans le condensateur de couplage de sortie C1 du stimulateur et dans la capacité C2 d'une seule électrode 14 de stimulation et de détection, ledit condensateur CI étant périodiquement déconnecté. L'invention s'applique à des stimulateurs cardiaques à fréquence fixe et à la demande, avec une seule électrode cardiaque.
