Why the study?
Can electrocardiographic features differentiate ventricular arrhythmias due to ARVD from those due to RVOTA?
Can electrocardiographic features differentiate ventricular arrhythmias due to ARVD from those due to RVOTA?
Specific ECG features, including QRS duration ≥125 ms in lead I and precordial R/S transition beyond V4, can help differentiate malignant ARVD arrhythmias from benign RVOTA.

Francis et al. (2015) conducted a review in Arrhythmogenic right ventricular dysplasia (ARVD) and right ventricular outflow tract arrhythmia (RVOTA). Electrocardiographic differentiation (QRS notching, QRS duration ≥125 ms, precordial R/S transition beyond V4) was evaluated on Differentiation of ARVD from RVOTA.
