Title (EN) LATENCY-BASED ADAPTATION OF ANTI-TACHYARRHYTHMIA PACING THERAPY
(FR) ADAPTATION FONDÉE SUR LATENCE DE THÉRAPIE DE STIMULATION ANTI-TACHYARYTHMIE
Abstract:
(EN) An implantable medical device comprises therapy delivery circuitry and processing circuitry. The therapy delivery circuitry is configured to deliver anti-tachycardia pacing (ATP) therapy to a heart of a patient. The ATP therapy includes one or more pulse trains and each of the one or more pulse trains includes a plurality of pacing pulses. The processing circuitry is configured to, for at least one of the plurality of pacing pulses of at least one of the one or more pulse trains, determine at least one latency metric of an evoked response of the heart to the pacing pulse. The processing circuitry is further configured to modify the ATP therapy based on the at least one latency metric.
(FR) La présente invention concerne un dispositif médical implantable comprenant un circuit d'administration de thérapie et un circuit de traitement. Le circuit d'administration de thérapie est conçu pour administrer une thérapie de stimulation anti-tachycardie (ATP) au cœur d'un patient. La thérapie ATP comprend un ou plusieurs trains d'impulsions et chacun du ou des trains d'impulsions comprend une pluralité d'impulsions de stimulation. Le circuit de traitement est conçu pour, pour au moins une impulsion parmi la pluralité d'impulsions de stimulation du ou des trains d'impulsions, déterminer au moins une métrique de latence d'une réponse évoquée du cœur à l'impulsion de stimulation. Le circuit de traitement est en outre conçu pour modifier la thérapie ATP sur la base de la ou des métriques de latence.
