Atrial Tachyarrhythmia in Arrhythmogenic Right Ventricular Cardiomyopathy: A Case Report.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardial condition that mostly affects the right ventricle (RV). Atrial involvement is poorly understood and the evidence for atrial involvement remains limited. In this case report, we describe an 18-year-old woman who had ARVC with the atrial tachyarrhythmia and initially presented with palpitations. As a rare disorder, ARVC requires a careful diagnosis to prevent unnecessary delays in patient care. In our case, the definitive diagnosis of ARVC was made as per Revised International Task Force Criteria 2010.
