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. http://dx.doi.org/10.4067/S0034-98872011000700014.
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.
