[Repolarization and intraventricular conduction disorders in arrhythmogenic right ventricular dysplasia].
Right ventricular dysplasia may lead to sudden cardiac death an adolescent or adult with little or no symptoms. Identification of this condition in the high-risk population appears to be an objective to be attained in the near future. Thorough ECG analysis seems to be a non-invasive and inexpensive technique which could be used as a first approach for screening of the disorder. In a series of 50 cases of arrhythmogenic right ventricular dysplasia compared with a control group, the diagnosis of ARVD could be determined by ECG with 84% sensitivity and 100% specificity if QRS duration in leads V1, V2 or V3 was longer than 110 ms, T wave was negative in V2 or if T wave was negative in V1, but in this latter case only provided incomplete right bundle branch block was present.
