[Ventricular extrasystole and arrhythmogenic right ventricular dysplasia. Critical analysis of the diagnostic value of non-invasive tests]. / Extrasystolie ventriculaire et dysplasie ventriculaire droite arythmogène. Analyse critique de la valeur diagnostique des examens non invasifs.

Asymptomatic ventricular extrasystoles were discovered in 2 active sportsmen (32 and 33 years). The cardiology work-up rapidly led to the diagnosis of arrhythmogenic right ventricular dysplasia in one. In the other, the clinical presentation was similar and the initial diagnosis was ventricular extrasystole with a healthy heart. Four years later however, the subject was still asymptomatic but a second evaluation revealed arrhythmogenic right ventricular dysplasia. This delayed diagnosis emphasizes the importance of renewed noninvasive evaluation of patients with asymptomatic ventricular extrasystoles.
