Premature ventricular complexes (PVCs) are common in the general population, usually a symptomatic, and deemed to be benign in structurally normal hearts. The spectrum of “benign” outflow tract PVCs ranges from single PVCs to recurrent non-sustained ventricular tachycardia (NSVT). Short-coupled right ventricular outflow tract (RVOT) PVCs may trigger polymorphic ventricular tachycardia (VT) in some patients and can be high risk. In many patients, PVCs can be more frequent and cause symptoms of palpitations, shortness of breath, dizziness, and heart failure.In the presence of underlying heart disease, they may indicate an increase drisk of adverse cardiovascular outcomes. A high PVC burden may lead to ventricular dysfunction and worsen underlying cardiomyopathy.PVCs may also be a marker of underlying pathophysiologic processes such as myocarditis and other acquired and inherited infiltrative cardiomyopathies. In this unique case report, we describe the use of a novel non-contact mapping array for mapping RVOT PVCs.
