Title
(EN) CARDIAC CONTRACTILITY MODULATION FOR ATRIAL ARRHYTHMIA PATIENTS
(FR) MODULATION DE LA CONTRACTILITÉ CARDIAQUE POUR DES PATIENTS ATTEINTS D'ARYTHMIE AURICULAIRE
Abstract
(EN)
A cardiac treatment device, including: stimulation circuitry configured to generate a non-excitatory electrical signal which, when applied to ventricular tissue during a ventricular refractory period thereof improves a condition of heart failure in human patients; atrial arrhythmia detection circuitry; and decision circuitry which controls the stimulation circuitry to delivery said signal, also when said atrial arrhythmia detection circuitry detects an atrial arrhythmia.
(FR)
L'invention concerne un dispositif de traitement cardiaque, comprenant : un circuit de stimulation conçu pour générer un signal électrique non excitateur qui, lorsqu'il est appliqué au tissu ventriculaire pendant une période réfractaire ventriculaire de celui-ci, améliore un état d'insuffisance cardiaque chez des patients humains ; des circuits de détection d'arythmie auriculaire ; et un circuit de décision qui commande les circuits de stimulation pour délivrer ledit signal, également lorsque ledit circuit de détection d'arythmie auriculaire détecte une arythmie auriculaire.
