Key result
In a patient with ARVC, epsilon waves appeared behind the QRS complex during sinus rhythm and apical VT, but preceded the QRS complex during VT originating from the right ventricular outflow tract.
Case Report (n=1)
No
In ARVC, the position of epsilon waves relative to the QRS complex during ventricular tachycardia depends on the origin of the arrhythmia.
No takes yet. Share an insight, caveat, or question.
May inform VT localization in ARVC; leaves open whether epsilon wave position is a reliable marker.
Pei et al. (2016) conducted a case report in Arrhythmogenic right ventricular cardiomyopathy (ARVC) (n=1). Arrhythmogenic right ventricular cardiomyopathy was evaluated. In a patient with ARVC, epsilon waves appeared behind the QRS complex during sinus rhythm and apical VT, but preceded the QRS complex during VT originating from the right ventricular outflow tract.
