Abstract

L'invention concerne un procédé et un appareil destiné à rythmer le coeur d'un patient à un rythme dépendant de son activité physique et de la position de son corps, en particulier lorsqu'il monte des escaliers. Un stimulateur cardiaque asservi comportant deux chambres comprend au moins un accéléromètre à courant continu monté dans le générateur d'impulsion du stimulateur cardiaque à implanter pour que l'axe sensible de l'accéléromètre à courant continu soit sensible aux effets de la gravité, lorsque le patient incline son corps vers l'avant pour prendre une position caractéristique de la montée d'un escalier. Les signaux de sortie en courant continu et en courant alternatif de l'accéléromètre sont traités pour produire un signal d'inclinaison et un signal d'activité. Un signal de commande de rythme cible est dérivé du signal d'activité qui est fonction du niveau d'activité. Une vitesse de monté des escaliers est choisie pour commander le rythme de stimulation physiologique entre un rythme supérieur et un rythme inférieur en présence d'un signal d'activité correspondant au rythme de marche du patient et d'un signal d'inclinaison tombant à l'intérieur d'une fenêtre d'inclinaison. Le signal de commande de rythme cible est utilisé pour assurer la commande du rythme de stimulation quand un signal d'activité indique un mouvement plus rapide du patient, par exemple, quand il court, ou quand le signal d'inclinaison est en dehors de la fenêtre d'inclinaison, ce qui indique que le patient est debout ou couché.
