Leadless pacemaker in Twiddler's syndrome: A case report.

ABSTRACT

Twiddler's syndrome is a rare cause of pacemaker lead dislodgement. We present the case of a 49-year-old male patient with Down's syndrome implanted with a dual chamber pacemaker showing high ventricular impedance, no sensing, and complete loss of capture for both leads at the 3-month follow-up due to Twiddler Syndrome. The dislocated device was removed, and an endocardial leadless pacing system was implanted.
