Abstract:
A 53year old lady was noted to have persistent bradycardia in the recovery unit shortly after a dual chamber permanent pacemaker (PPM) was implanted. The patient was asymptomatic. The pacemaker was implanted for symptomatic intermittent complete heart block. She had surgical closure of an atrial septal defect three decades earlier and a previous tricuspid valve replacement with concomitant biatrial cryomaze procedure for paroxysmal atrial fibrillation.
