no. 1 Embodiment

[0067] In order to facilitate the reading of this application manual, the English abbreviations appearing in the text are explained as follows: the heart is composed of an atrium (atrial) and a ventricle (ventricle). Finally, the heart relaxes again, and so on.

[0068] PMT is pacemaker-mediated tachycardia; PVARP is post-ventricular atrial refractory period; ARS is atrial refractory period sensing event, and in this application specifically refers to an atrial sensing event occurring in PVARP.

[0069] AS stands for atrial sensing event; AP stands for atrial pacing event; ARS stands for atrial refractory period sensing event, specifically refers to atrial sensing event occurring in PVARP in this application; VS stands for ventricular sensing event; VP stands for ventricular pacing event; PVC Represents premature ventricular contraction event; PAC represents premature atrial contraction event; PVC-AS represents the time interval from PVC event to AS event; VP-PAC represents th...

Abstract

The invention relates to the field of medical instruments, in particular to a PMT inducement detection and prevention method, a storage medium and a pacemaker system and device. The pacemaker mediatedtachycardia is also called PMT, and is a kind of pacemaker-induced tachycardia. The PMT inducement detection and prevention method provided by the application mainly comprises the following steps: terminating suspected PMT, confirming PMT, identifying different PMT inducements, and executing a preset prevention measure based on the different PMT inducements. The application provides a pacemaker system. The system comprises a battery, a power management module, a communication circuit module, a sensing circuit module and a pacing circuit module, and further comprises a PMT inducement detectionand prevention module. The PMT inducement detection and prevention system mainly comprises a rolling intracardiac electrogram (IEGM) electrocardio data acquisition module, a PMT termination and identification module, a PMT inducement identification module and a PMT inducement storage module.

Description

technical field [0001] The present application relates to the field of medical devices, in particular, to a PMT inducement detection and prevention method, storage medium, and pacemaker system and device. Background technique [0002] Pacemaker-mediated tachycardia (PMT) is a pacemaker-induced tachycardia in which ventricular activation is propagated through ventriculoatrial retrograde following a premature ventricular contraction (PVC) or depolarization of the ventricles by a pacing pulse Atrial activation is caused, and then, if there is no spontaneous ventricular activity during the AV interval set by the pacemaker, the pacemaker will send a ventricular pacing pulse at the end of the AV interval, and this ventricular activation will be reversed again to cause atrial activation, This recurring heart muscle activity is called reentrant tachycardia. From the perspective of the above-mentioned mechanism of PMT, patients with pathological or physiological ventricular retrogra...
