A 76-yr-old man with unipolar ventricular pacemaker, previously
implanted in the right ventricular apex, presented with
syncopal attack and twitching of the right pectoralis muscle.
He finally was diagnosed as having Twiddlerיs syndrome. The
patient had a pulse rate of 36/min and cannon waves in the
neck veins. Chest radiography showed a dislodged pacing lead
completely wrapped around the pulse generator. After uncoiling
the lead it was positioned in the right ventricular apex and
the pulse generator implanted and sewed tightly in a smaller
pocket. After six months follow-up there was no further twiddling
or pacemaker dysfunction
