Objective. To present a review of the literature and a clinical example of the Wolf-Parkinson-White phenomenon in a child involved in sports.

Methods. A clinical example of the Wolf-Parkinson-White phenomenon in a child is described. A lesion of heart conductivity was initially found by cardiologist examination where the patient applied to solve the question whether he could continue doing sports. The results of a complex examination are presented: standard ECG, daily monitoring ECG, load test, intra-esophageal electrophysiology study.

Results. According to standard ECG and Holter monitoring ECG, we found alteration of of sinus rhythm with normal atrioventricular conductivity and QRS complexes of the WPW type, with a frequency of 1: 1. Under the load we registered mainly sinus rhythm with normal atrioventricular conductivity and under restitution – preexcitation syndrome. During non-invasive electrophysiology study, the paroxysm of supraventricular tachycardia was not induced. Effective refractrory period of additional atrioventricular connection was 320 ms.

Conclusions. The obtained data enabled to estimate the risk of atrial fibrillation and sudden death as low. The child was recommended low-static physical load with low and middle dynamic component. Children with Wolf-Parkinson-White syndrome engaged in sports are recommended to undergo complex examination  to determine the degree of risk of emergency states and optimal training regime.

Key words: WPW pattern, sport, children.
