Title
(EN) TERMINATING PACEMAKER MEDIATED TACHYCARDIA (PMT) IN DUAL CHAMBER LEADLESS PACEMAKER SYSTEM
(FR) TERMINAISON DE TACHYCARDIE INDUITE PAR UN STIMULATEUR CARDIAQUE (PMT) DANS UN SYSTÈME DE STIMULATEUR CARDIAQUE SANS FIL À DOUBLE CHAMBRE
Abstract
(EN)
An implantable system including an atrial leadless pacemaker (aLP) and a ventricular leadless pacemaker (vLP), and methods for use therewith, are configured or used to terminate a pacemaker mediated tachycardia (PMT). One of the aLP or the vLP detects a PMT and informs the other one. The aLP initiates a PMT PA interval that is shorter than a PA interval that the aLP would otherwise use for atrial pacing if a PMT was not detected. The vLP initiates a PMT PV interval that is longer than the PMT PA interval. If an intrinsic atrial or ventricular event is detected before PMT PA interval or the PMT PV interval expires, then these intervals will be terminated, otherwise an atrial chamber will be paced if the PMT PA interval expires, and/or a ventricular chamber will be paced if the PMT PV interval expires. This should have the effect of terminating the PMT.

La présente invention concerne un système implantable comprenant un stimulateur cardiaque sans fil auriculaire (aLP) et un stimulateur cardiaque sans fil ventriculaire (vLP), et des procédés destinés à être utilisés avec celui-ci, qui sont configurés ou utilisés pour mettre fin à une tachycardie induite par un stimulateur cardiaque (PMT). L'aLP ou le vLP détecte une PMT et en informe l'autre. L'aLP déclenche un intervalle PA de PMT qui est plus court qu'un intervalle PA que l'aLP pourrait autrement utiliser pour la stimulation auriculaire si aucune PMT n'était détectée. Le vLP déclenche un intervalle PV de PMT qui est plus long que l'intervalle PA de PMT. Si un événement auriculaire ou ventriculaire intrinsèque est détecté avant l'expiration de l'intervalle PA de PMT ou de l'intervalle PV de PMT, alors ces intervalles prendront fin ; sinon, une chambre auriculaire sera stimulée si l'intervalle PA de PMT expire, et/ou une chambre ventriculaire sera stimulée si l'intervalle PV de PMT expire. Cela devrait avoir pour effet de mettre fin à la PMT.
