Title (EN) CONDUCTION PATHWAY DRIVEN MULTI-SITE PACING APPARATUS
(FR) APPAREIL DE STIMULATION MULTISITE ENTRAÎNÉ PAR VOIE DE CONDUCTION
Abstract:
(EN) An apparatus comprises a stimulus circuit, a cardiac signal sensing circuit, and a control circuit. The cardiac signal sensing circuit senses a cardiac activity signal using a sensing channel. The stimulus circuit provides electrical pulse energy to a first pacing channel that includes a first left ventricular (LV) electrode and a second pacing channel that includes a second LV electrode. The control circuit initiates delivery of electrical pulse energy using the first and second pacing channels according to a first multi-site LV pacing mode; determines a cardiac event associated with a change in cardiac conduction path using a sensed cardiac activity signal; and changes to a second LV pacing mode in response to determining the cardiac event. The second LV pacing mode is different from the first multi-site LV pacing mode in one or more of a pacing site location and inter-electrode stimulus timing.
(FR) La présente invention concerne un appareil qui comprend un circuit de stimulus, un circuit de détection de signal cardiaque, et un circuit de commande. Le circuit de détection de signal cardiaque détecte un signal d'activité cardiaque à l'aide d'un canal de détection. Le circuit de stimulus fournit une énergie d’impulsion électrique à un premier canal de stimulation qui comprend une première électrode ventriculaire gauche (LV) et un deuxième canal de stimulation qui comprend une deuxième électrode LV. Le circuit de commande déclenche l'administration d'énergie d'impulsion électrique à l'aide des premier et deuxième canaux de stimulation selon un premier mode de stimulation LV multi-site ; détermine un événement cardiaque associé à un changement du trajet de conduction cardiaque à l'aide d'un signal d'activité cardiaque détecté ; et change pour un deuxième mode de stimulation LV en réponse à la détermination de l'événement cardiaque. Le deuxième mode de stimulation LV diffère du premier mode de stimulation LV multi-site par un ou plusieurs d'un emplacement de site de stimulation et d'une synchronisation de stimulus entre électrodes.
