Noninvasive cardiac screening in young athletes with ventricular arrhythmias.
Bottom Line: Results of ECG were normal in most athletes (85%).Overall, 30% of athletes were judged to have potentially dangerous VAs.In conclusion, cardiac screening with noninvasive examinations remains a fundamental tool for the identification of a possible pathologic substrate and for the characterization of electrical instability.

Mentions: After clinical evaluation, 30% of athletes were judged to have potentially dangerous VAs on the basis of the presence of a morphologic substrate and/or the characteristics of VA pattern according to the recommendations for competitive sports, tailored to each athlete and type of sport10–12 (Figure 2). Borderline cases belonging to the “gray zone” of diagnosis between athlete's heart and arrhythmogenic RV cardiomyopathy were also judged potentially dangerous. Among these athletes, 10% (n = 14) were treated with antiarrhythmic drugs, in 1.4% (n = 2) ablation was indicated, and in 1 athlete surgical repair of the congenital defect was indicated. In the rest of the athletes, competitive sports were not recommended, and detraining was proposed (n = 26). Follow-up was feasible in 93 athletes (mean 28 months). A decrease of >70% in the number of PVCs compared to the first Holter monitoring was observed in 34 (37%), while in 31 (33%), VAs did not show significant changes, and in 28 (30%), PVCs increased. During follow-up, no athlete presented with a major cardiac event.
