Key result
Pacemaker malfunction due to loss of ventricular capture can result from a poor connection between the lead pin and connector header, presenting as symptomatic bradycardia.
Case Report (n=1)
Highlights a rare cause of pacemaker malfunction due to poor connection between the lead pin and connector header resulting in loss of ventricular capture.

Clinicians should consider lead-header integrity in unexplained loss of capture; case reports leave open true incidence and prevention.
Pacemaker malfunctions are due to multiple reasons like lead dislodgement, lead perforation, lead maturation process, lead conductor or insulation failure, battery depletion, loose set screw and inadequate seating of terminal connector pin within connector block. We report a case of the 57-year-old female, who underwent dual chamber pacemaker implantation few years back for complete heart block and this time she presented to us with symptomatic bradycardia. After pacemaker interrogation, electrocardiogram and chest X-ray, the final diagnosis of pacemaker malfunction due to loss of ventricular capture as a result of the poor connection between the lead pin and connector header was made.

Sondhi et al. (2018) conducted a case report in Pacemaker malfunction (n=1). Pacemaker interrogation, electrocardiogram, and chest X-ray was evaluated on Diagnosis of pacemaker malfunction. Pacemaker malfunction due to loss of ventricular capture can result from a poor connection between the lead pin and connector header, presenting as symptomatic bradycardia.
