These included the documentation of sustained VT of the morphology described in Table 1 (arrhythmia criteria), the presence of epsilon waves (depolarization criteria) and T-wave inversions in [V.
After DC, control ECG showed right bundle branch block with epsilon wave in V1 and ST segment depression in precordial leads (V2-V4) (Fig.
Twelve-lead electrocardiogram (ECG) showed inverted T waves and epsilon wave in VI-V4 (Fig.
Epsilon wave is detected in 5-30% of the cases and if present, it is a pathognomonic for ARVC (6).
On admission, the electrocardiogram showed that T-wave inversions were visible in most leads, QRS duration was prolonged with 120 ms, and the terminal depolarizations might be interpreted as epsilon waves in leads V1–V5 [Figure 1]a arrows].
Epsilon waves were observed in the probands carrying the mutation in the genes coding for the desmosomal proteins but not in the patients with TGF/3-3 gene mutation (12).
