%X Cardiovascular remodeling in a trained athlete is frequently associated with ECG patterns related to physiological adaptation to exercise (so-called athlete's heart). ECG changes overlap significantly with ECG abnormalities seen in the cardiovascular disease which cause sudden death. However, sometimes ECG abnormalities that reflect underlying heart disease and indicate an increased risk of arrhythmic cardiac arrest during sport may be detected. This report describes a case of a 32-year-old male, competitive athlete with atypical repolarization pattern in ECG. QTc measured in rest ECG was 610 ms and maladaptation of the QT interval duration to the changing heart rate was documented. 24-hour ECG did not show significant arrhythmias. Both echocardiogram and magnetic resonance confirmed structurally normal heart. Electrophysiological study ruled out WPW syndrome, atrio-ventricular 1:1 conduction was normal. HUT result was normal. Finally the diagnosis of ""potential LQTS"" was established and the patient was advised not to participate in competitive sports. Review of the literature and clinical implications are discussed.
