Abstract

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.
