What could be the cause of late syncope after pacemaker implantation?
A 21-year-old man who had suffered an episode of complete heart block 2 months earlier and thus undergone pacemaker implantation presented with syncope. Echocardiography showed cardiac tamponade and raised the suspicion of lead penetration. The effusion was drained. Multi-sliced CT scan confirmed that the right aspect of the pacemaker wire was extracardiac, causing the cardiac tamponade.
