Title (EN) METHOD AND APPARATUS TO ENSURE CONSISTENT LEFT VENTRICULAR PACING
(FR) MÉTHODE ET APPAREIL ASSURANT UN RYTHME CONSTANT DU VENTRICULE GAUCHE
Abstract: front page image
(EN)A method of operating a cardiac therapy system to deliver cardiac resynchronization therapy (CRT) pacing that includes pacing both ventricles or pacing only the left ventricle is described. Delivery of the CRT pacing to one or both ventricles is scheduled for a cardiac cycle. If an intrinsic depolarization of a ventricle is detected during a pacing delay of the ventricle, then the scheduled CRT pacing to the ventricle is inhibited for the cycle. The intrinsic interval of the ventricle, such as the intrinsic atrioventricular interval concluded by the intrinsic depolarization, is measured. During a subsequent cardiac cycle, the pacing delay of the ventricle is decreased to be less than or equal to the measured intrinsic interval. Capture of the ventricle is verified after pacing is delivered during the subsequent cardiac cycle.
(FR)L'invention porte sur une méthode de mise en oeuvre d'un système de thérapie cardiaque délivrant des stimulations de thérapie de resynchronisation cardiaque pouvant réguler le rythme des deux ventricules ou du seul ventricule gauche. La délivrance de la stimulation CRT à un ventricule ou aux deux se fait sur un cycle cardiaque. Si une dépolarisation intrinsèque d'un ventricule est détectée pendant un retard de stimulation du ventricule, la stimulation CRT prévu du ventricule est supprimée pour le cycle. On mesure l'intervalle intrinsèque du ventricule, par exemple l'intervalle atrioventriculaire intrinsèque se terminant par la dépolarisation intrinsèque, et pendant le cycle cardiaque suivant, le retard de stimulation du ventricule est réduit pour être inférieur ou égal à l'intervalle intrinsèque mesuré. La capture du ventricule est vérifiée après délivrance de la stimulation pendant le cycle cardiaque suivant.
