Title
(EN) METHOD AND DEVICE FOR DELIVERING MULTI-PHASE DEFIBRILLATION THERAPY
(FR) MÉTHODE ET DISPOSITIF POUR ADMINISTRER UNE THÉRAPIE DE DÉFIBRILLATION À PHASE MULTIPLE
Abstract
(EN) Methods and systems are provided that comprise: sensing cardiac events of a heart; utilizing one or more processors to perform: declaring a ventricular fibrillation (VF) episode based on the cardiac events charging a single charge storage capacitor; delivering a multi-phase VF therapy that includes phase I and phase II therapies, wherein: a) during the phase I therapy, a combination of two or more medium voltage (MV) shocks are delivered entirely from the single charge storage capacitor; and b) during the phase II therapy, a low voltage pulse train is delivered at least partially from the single charge storage capacitor. Methods and systems are provided that comprise delivering first and second pulses of at least a first biphasic shock, wherein a parallel - series reconfiguration circuit connects and configures the capacitors of the capacitor bank in a parallel configuration to deliver a parallel biphasic shock; connecting the capacitors of the capacitor bank in a series configuration; and delivering first and second pulses of a second biphasic shock while the capacitors are connected in series to deliver a series biphasic shock.
(FR) L'invention concerne des méthodes et des systèmes qui consistent à : détecter des événements cardiaques d'un cœur ; utiliser un ou plusieurs processeurs pour effectuer : la déclaration d'un épisode de fibrillation ventriculaire (VF) sur la base d'événements cardiaques chargeant un seul condensateur de stockage de charge ; administrer une thérapie de VF à phase multiple qui comprend des thérapies de phase I et de phase II : a) pendant la thérapie de phase I, une combinaison d'au moins deux chocs de tension moyenne (MV) étant administré entièrement à partir du condensateur de stockage de charge unique ; et b) pendant la thérapie de phase II, un train d'impulsions basse tension étant administré au moins partiellement depuis le condensateur de stockage de charge unique. L'invention concerne des procédés et des systèmes qui consistent à administrer des première et seconde impulsions d'au moins un premier choc biphasique, un circuit de reconfiguration en série-parallèle connectant et configurant les condensateurs du banc de condensateurs selon une configuration parallèle pour administrer un choc biphasique parallèle ; connecter les condensateurs du banc de condensateurs dans une configuration en série ; et administrer des première et seconde impulsions d'un second choc biphasique tandis que les condensateurs sont connectés en série pour délivrer un choc biphasique en série.
