Inappropriate pacing in a patient with managed ventricular pacing: What is the cause?

Inappropriate pacing in a patient with managed ventricular pacing: What is the cause? HEART RHYTHM Perez, M. V., Al-Ahmad, A. A., Wang, P. J., Turakhia, M. P. 2010; 7 (9): 1336-1337

Abstract

A case of inappropriate atrial pacing in a patient with a pacemaker programmed with Managed Ventricular Pacing (MVP) mode, a proprietary algorithm in Medtronic devices, is presented. The patient was an 84-year-old woman who presented in sinus rhythm with complete atrioventricular block. A dual-chamber pacemaker was implanted and programmed to an MVP pacing mode. After the implant, the patient developed a relatively slow atrial tachyarrhythmia with 2:1 atrioventricular block and inappropriate atrial pacing, followed by a delay in tracking of the atrial tachyarrhythmia. The mechanisms for these behaviors are described.
