Abstract
We report a 26 year 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.

Esto conduce a falla de sensado y captura de él o los electrodos de estimulación, por pérdida del contacto electrodo-tisular con el miocardio
El diagnóstico se confirma con una radiografía de tórax, en la cual se comprueba la rotación del generador dentro del bolsillo, el desplazamiento de los electrodos endocavitarios y el enrollamiento de éstos entorno al generador
Summary
We report a 26 year old patient who had a single chamber pacemaker implantation one year before. El síndrome de Twiddler fue descrito en 1968 y hace referencia a una disfunción del marcapaso debido a pérdida del contacto electrodo-tisular a nivel del miocardio, secundario a tracción y enrollamiento de los electrodos de estimulación en el bolsillo del implante, por manipulación del generador por parte del paciente[1]. A continuación presentamos el caso de un paciente con disfunción de marcapaso secundaria a este síndrome.
