Permanent pacemaker (PPM) malfunction due to electrical connection problems such as a loose set screw or lead-header malapposition is extremely rare. We present a patient with complete heart block (CHB) who had PPM malfunction and recurrent syncope, late (14 months) after initial implantation, which was caused by the ventricular lead pin disengagement from the header resulting in oversensing due to noise, pacing inhibition and recurrent syncope. PPM due to lead-header malapposition this late after device implantation has previously not been reported.
