Title
(EN) SYSTEMS AND METHODS FOR OPTIMIZING CARDIAC RESYNCHRONIZATION THERAPY (CRT)
(FR) SYSTÈMES ET PROCÉDÉS D'OPTIMISATION D'UNE THÉRAPIE DE RESYNCHRONISATION CARDIAQUE (TRC)
Abstract
(EN) Systems and methods for optimizing CRT are disclosed. According to an aspect, a method includes receiving, during at least two time periods of a cardiac cycle, electrical signals communicated by two or more electrodes of a CRT device positioned one or more of on a surface of a body, within a thorax of the body, a heart of the body, a surrounding venous structure of the body, and a surrounding subcutaneous structure of the body. The method also includes calculating, based on the received electrical signals, spacing between the two or more electrodes during the at least two time periods of the cardiac cycle. Further, the method includes controlling output of the CRT device to the electrodes based on the calculated spacing between the two or more electrodes.
(FR) La présente invention concerne des systèmes et des procédés d'optimisation d'une TRC. Selon un aspect, un procédé comprend les étapes consistant à recevoir, pendant au moins deux intervalles de temps correspondant à un cycle cardiaque, des signaux électriques communiqués par au moins deux électrodes d'un dispositif de CRT qui sont positionnées sur une ou plusieurs surfaces de l'organisme, dans le thorax, le cœur, une structure veineuse voisine et une structure sous-cutanée voisine de l'organisme. Ledit procédé comprend également les étapes consistant à calculer, sur la base des signaux électriques reçus, l'espacement entre lesdites au moins deux électrodes durant lesdits au moins deux intervalles de temps correspondant à un cycle cardiaque. Le procédé comprend, en outre, une étape consistant à réguler la puissance fournie par le dispositif de CRT aux électrodes sur la base de l'espacement calculé entre lesdites au moins deux électrodes.
