title: Dislodgment of pacemaker electrode simulating focal motor seizure.
abstract: The unusual finding of dislocation of the electrode of a pacemaker in a patient caused repetitive twitching of the right leg. Initial confusion with focal motor seizure resulted in the administration of antiepileptic medication. Malposition of the electrode was confirmed by appropriate roentgenographic studies, and subsequent repositioning terminated the episode.
