Reel syndrome and pulsatile liver in a patient with a two-chamber pacemaker.

Twiddler's syndrome is characterized by coiling of the pacemaker lead due to the rotation of the pacemaker generator on its long axis. Reel syndrome is another form of Twiddler's syndrome. It occurs due to the rotation of the pacemaker generator on its transverse axis with subsequent coiling of the pacemaker leads around the pulse generator. In this article we describe a patient with a two-chamber pacemaker who presented with sudden onset of abdominal pulsation and was subsequently diagnosed as Reel syndrome. To the best of our knowledge, this case is the first case of Reel syndrome that developed in a patient with a two-chamber pacemaker.
