Targeted interventions successfully resolved competitive ventricular pacing caused by the accidental reactivation of a retained pacemaker two years after device replacement.
Case Report (n=1)
Highlights a rare case of competitive ventricular pacing due to accidental reactivation of a retained pacemaker and its successful resolution.
Herein, we report a rare clinical case of competitive ventricular pacing caused by the accidental reactivation of a retained pacemaker two years after device replacement. Initially, two years following the implantation of the new pacemaker, the device demonstrated typical dual-chamber pacing. However, recent follow-up electrocardiography revealed two distinct QRS morphologies. Holter monitoring, imaging studies, and a review of prior procedural records confirmed that this phenomenon was caused by the unexpected reactivation of the retained pacemaker, leading to competitive ventricular pacing. A detailed analysis of the underlying causes of inadvertent reactivation led to the implementation of targeted interventions, which successfully resolved the issue of competitive ventricular pacing induced by dual pacemakers.
Wu et al. (2026) conducted a case report in Competitive ventricular pacing (n=1). Targeted interventions for pacemaker deactivation was evaluated on Resolution of competitive ventricular pacing. Targeted interventions successfully resolved competitive ventricular pacing caused by the accidental reactivation of a retained pacemaker two years after device replacement.
