High Interobserver Variability in the Assessment of Epsilon Waves: Implications for Diagnosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia.
Revision of the Task Force diagnostic criteria (TFC) for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) has increased their sensitivity for diagnosis of early and familial forms of the disease. Epsilon wave (EW) is a major diagnostic criterion in the context of ARVC/D, which, however, remains not quantifiable and therefore may leave room for substantial subjective interpretatio
