Abstract

L'INVENTION CONCERNE UN GENERATEUR D'IMPULSIONS DE STIMULATEUR CARDIAQUE. IL COMPORTE UN CIRCUIT D'HORLOGE QUI DELIVRE UNE SERIE D'IMPULSIONS D'HORLOGE, UN COMPTEUR QUI COMPTE CES IMPULSIONS ET UN CIRCUIT LOGIQUE COMMANDE PAR LE COMPTEUR LORSQU'IL ATTEINT UN PREMIER COMPTAGE DE MANIERE A EMETTRE UNE IMPULSION DE STIMULATION CARDIAQUE ET A RAMENER LE COMPTEUR AU REPOS, ET COMMANDE EGALEMENT PAR LE COMPTEUR LORSQU'IL ATTEINT UN SECOND COMPTAGE INFERIEUR AU PREMIER, APRES L'EMISSION DE L'IMPULSION DE STIMULATION, DE MANIERE A INTERROMPRE L'EMISSION DE CETTE IMPULSION. L'INVENTION S'APPLIQUE NOTAMMENT A DES STIMULATEURS CARDIAQUES IMPLANTABLES.
