Abstract

A 56-year-old man with an implantable cardioverter-defibrillator (ICD) presented with unexplained heart palpitations, which were usually aggravated after ingesting alcohol. He had a history of coronary artery bypass graft surgery 8 years ago, and an ICD was placed (i.e. a single ventricular shock coil with integrated atrial-sensing rings [VDD ICD lead]) 1.5 years ago for primary prevention of sudden cardiac death associated with ischemic cardiomyopathy. Repeated electrocardiograms and echocardiograms showed no evidence of atrial flutter-fibrillation; this was clearly demonstrated using several atrial electrogram strips during the ICD analysis.
