BACKGROUND: Epsilon wave is a major criteria for arrhythmogenic right ventricular (RV) dysplasia/cardiomyopathy (ARVD/C). We sought to study systematically characteristics of Epsilon wave in ARVD/C patients from the southern Chinese population. METHODS: The population included 49 patients with ARVD/C meeting the diagnostic criteria. They were analyzed for the value of different electrocardiogram (ECG) criteria including Epsilon wave, the ones of 24-hour Holter recording, signal-averaged ECG, and echocardiography to learn the correlation between Epsilon wave and other variability with the use of nonparametric test. A probability value of < or =0.05 was considered significantly different. RESULTS: It shown that the detection rate of Epsilon wave was significantly higher in probands (65%) than involved family members (22%), P = 0.03. In the conventional as well as Fontaine leads, its detection rate were 18 (37%) and 28 (57%), respectively. The prevalence of diffuse right ventricle involvement, T-wave inversion and signal-averaged ECG are significantly different between the ARVD/C patients with Epsilon wave and without Epsilon wave. CONCLUSION: It is significantly correlated between Epsilon wave and the progressive ARVD/C.
