RAMIREZ E, Pablo et al. Twiddler syndrome: Report of one case. Rev. méd. Chile [online]. 2011, vol.139, n.7, pp.917-919. ISSN 0034-9887.

We report a 26year old patient who had a single chamber pacemaker implantation one year before. During a routine pre-operative evaluation, pacemaker dysfunction was demonstrated due to sensing and pacing failure, associated to left pectoral muscle rhythmic contraction. Chest X-ray confirmed Twiddler syndrome, in which twisting or rotation of the device inside the pocket results in lead dislodgement and device malfunction.

Keywords : Arrhythmias, cardiac; Pacemaker, artificial; Twiddler syndrome.
