title: [Redetection of tachycardia in severe ventricular undersensing].
abstract: In a 50-year-old patient with arrhythmogenic right ventricular cardiomyopathy (ARVC) and implantable cardioverter defibrillator (ICD) two shock discharges occurred after several ineffective attempts with antitachycardia pacing. The analysis of the stored electrograms shows a peculiarity of shocks with low energy, a problem of ICD therapy in ARVC, and the impact of committed shocks as opposed to non-committed shocks.
