Abstract des Autors

Isolated ventricular ectopies are relatively common in pediatric age. Usually these arrhythmias have a left bundle branch morphology, are suppressed by exercise and have a very good long-term prognosis. Rarely ventricular ectopies could be expression of more serious arrhythmic problems as idiopathic ventricular tachycardia, right ventricle displasia, long QT syndrome. Subjects with isolated ventricular ectopies, engaged in competitive sports, should have a complete cardiological evaluation with ECG, stress test, Holter monitoring, to allow the identification of high risk patients. Unclear is the prognosis of subjects with numerous isolated ventricular ectopies and/or polymorphic ectopies, but our data shows as these last patients have a good long-term prognosis remaining asymptomatic without repetitive ventricular arrhythmias. In conclusion, competitive sports may be allowed in all subjects with isolated ventricular ectopies only after the exclusion of major arrhythmic pathology. More caution should be reserved for subjects with polymorphic ectopies and/or with ectopies which increase in number with effort. Verf.-Referat
