Title (EN) METHODS AND SYSTEMS FOR MITIGATING THE OCCURRENCE OF ARRHYTHMIA DURING ATRIAL PACING
(FR) PROCÉDÉS ET SYSTÈMES POUR ATTÉNUER L'APPARITION D'ARYTHMIE DURANT UNE STIMULATION AURICULAIRE
Abstract:
(EN) Noncaptured atrial paces can result in long-short cardiac cycles which are proarrhythmic for ventricular tachyarrhythmia. Approaches are described which are directed to avoiding proarrhythmic long-short cycles. For cardiac cycles in which the atrial pace captures the atrium, a first post ventricular refractory period (PVARP) and a first A-A interval are used. For cardiac cycles in which the atrial pace does not capture the atrium, both an extended PVARP and an extended A-A interval are used. The A-A interval following a noncaptured atrial pace is extended from an atrial depolarization sensed during the extended PVARP.
(FR) Des stimulations auriculaires non capturées peuvent conduire à des cycles cardiaques longs-courts, qui sont proarythmiques pour la tachyarythmie ventriculaire. Des approches sont décrites, lesquelles visent à éviter des cycles longs-courts proarythmiques. Pour les cycles cardiaques dans lesquels la stimulation auriculaire capture l'oreillette, une première période réfractaire post-ventriculaire (PVARP) et un premier intervalle A-A sont utilisés. Pour les cycles cardiaques dans lesquels la stimulation auriculaire ne capture pas l'oreillette, à la fois une PVARP prolongée et un intervalle A-A prolongé sont utilisés. L'intervalle A-A suivant une stimulation auriculaire non capturée est prolongé à partir d'une dépolarisation auriculaire détectée durant la PVARP prolongée.
