Abstract

BACKGROUND AND OBJECTIVES: The electrocardiography (ECG) morphology of lead aVR has been associated with arrhythmic risk in Brugada syndrome, but its role in arrhythmogenic right ventricular cardiomyopathy (ARVC) remains unclear. To evaluate the clinical significance of aVR morphology in ARVC patients. METHODS: A total of 45 subjects diagnosed with ARVC who underwent epicardial-endocardial mapping were enrolled in the study. The patients were divided into two groups based on the presence of an epicardial right ventricular outflow tract (RVOT) scar: the n-RVOT group (scar area
