Abstract

This report describes a patient who underwent cardiac resynchronization complicated by a Twiddler syndrome. This caused triple atrial sensing and an inappropriate shock.

Keywords: Twiddler syndrome; cardiac resynchronization; implantable cardioverter‐defibrillator; pacemaker; ventricular tachycardia.
