Implantable cardioverter defibrillators (ICDs) are frequently offered to patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). Yet ICDs in these patients may be complicated by poor sensed amplitudes resulting from fatty and fibrous tissue replacement of right ventricular myocardium. We present the case of a patient with ARVD/C who had inappropriate detection of ventricular tachycardia with a single-chamber ICD due to poor sensed right ventricular amplitudes. We discuss how the use of a bipolar coronary sinus lead and a biventricular ICD generator with a novel header configuration solved the problem.
