Figure 1.

Twelve-lead ECG and Twelve-lead Holter recording images of patients with ARVD. (a) Twelve-lead ECG demonstrated epsilon waves (blue arrows) in precordial leads. (b) Twelve-lead Holter recording demonstrated PVCs in a 15-year-old patient; LBBB with the inferior axis (red arrows) and RBBB with the superior axis (blue arrows). (c) Twelve-lead ECG demonstrated VT with large QRS with left branch block superior axis.

ARVD - arrhythmogenic right ventricular dysplasia, ECG - electrocardiography, LBBB - left bundle-branch block, PVCs - premature ventricular contractions, RBBB - right bundle-branch block
