Title
(EN) CAPTURE IN VENTRICLE-FROM-ATRIUM CARDIAC THERAPY
(FR) CAPTURE DANS UNE THÉRAPIE CARDIAQUE DU VENTRICULE À PARTIR DE L'OREILLETTE
Abstract
(EN)
Ventricle-from-atrium (VfA) cardiac therapy may utilize a tissue-piercing electrode implanted in the left ventricular myocardium of the patient's heart from the right atrium through the right atrial endocardium and central fibrous body. The exemplary devices and methods may determine whether the tissue-piercing electrode is achieving effective left ventricular capture. Additionally, one or more pacing parameters, or paced settings, may be adjusted in view of the effective left ventricular capture determination.
(FR)
La présente invention concerne une thérapie cardiaque du ventricule à partir de l'oreillette (VaO) qui peut utiliser une électrode de perforation de tissu implantée dans le myocarde ventriculaire gauche du cœur du patient à partir de l'oreillette droite à travers l'endocarde auriculaire droit et le corps fibreux central. Les dispositifs et procédés à titre d'exemples peuvent déterminer si l'électrode de perforation de tissu parvient ou non à une capture ventriculaire gauche efficace. De plus, un ou plusieurs paramètres de stimulation, ou réglages stimulés, peuvent être ajustés en vue de la détermination d'une capture ventriculaire gauche efficace.
