Abstract: | The original 1994 International Task Force criteria for the clinical diagnosis of arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC / D) were based on structural,histological,ECG,arrhythmic,and familial features of the disease (Table 1).Abnormalities were subdivided into major and minor categories according to the specificity of their association with ARVC / D.Right precordial T-wave inversion,though well recognized in ARVC / D,was considered a minor criterion because of its presence in other conditions,including anterior ischemia and right ventricular (RV) hypertrophy.Arrhythmias of RV origin,another cardinal feature of ARVC / D,was designated a minor criterion because of its occurrence in other diseases,particularly idiopathic RV outflow tract tachycardia. |
