DIAZ, Juan C. et al. Ventricular electrode rupture due to twiddler's syndrome. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.3, pp.228.e1-228.e4. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.11.005.

Twiddler's syndrome is characterised by a twist and displacement of the electrodes of a cardiac stimulation device due to a rotation on its main axis, either spontaneously or when manipulating the pacemaker. In most cases this movement is accompanied by damage of the electrode; however, complete rupture of the lead has not been described. A case of a patient carrying a unicameral pacemaker required due to slow atrial fibrillation is now described, where a dysfunction of the device was documented as a failure to detect and capture. Upon interrogation the patient manifested asthenia, adynamia, exercise intolerance and pre-syncope. Radiological assessment documented a twisted electrode with the shape of tight handles, with complete electrode rupture and displacement of the pacemaker generator in a wide pocket. According to the authors’ criteria, this is the first Twiddler's syndrome case where total rupture of an electrode has been documented.
