A 29-year-old man received a Lumax 340 VRT XL implantable cardioverter defibrillator (ICD) connected to a Linox S 65 single-coil true bipolar shock lead (BIOTRONIK SE &CO, KG, Berlin, Germany) in 2008 after successful resuscitation from sustained ventricular tachycardia (VT). An underlying Brugada syndrome (BS) was diagnosed. At implant R-wave sensing was 12.5 mV. Tachycardia detection was programmed as follows: VT monitoring zone between 180 beats/min and 240 beats/min and ventricular fibrillation (VF) zone for rates above 240 beats/min. VF induction was performed and showed correct sensing at least sensitivity. The patient remained asymptomatic until November 2012 when he experienced an ICD shock during strenuous exercise (Fig. 1). Is this an appropriate or inappropriate shock and what is the cause of the shock?
