Abstract		Electrocardiogram (ECG) is being increasingly used as part of cardiovascular preparticipation screening of young competitive athletes (under 35 years of age) since it significantly increases the sensitivity of such screening compared to history and clinical examination alone. It has become part of a common European protocol for cardiovascular preparticipation screening of young competitive athletes. For a proper interpretation of ECG changes, it is crucial to be familiar with ECG abnormalities in cardiovascular diseases causing sudden cardiac death, and with normal variants of athlete's ECG, originating from their adaptations to intense athletic training. Structural adaptations (increased heart chamber size and mass) often result in isolated voltage criterion for left ventricular hypertrophy and incomplete right bundle branch block, while functional adaptations (mainly heightened parasympathetic tone) result in rhythm disorders (sinus bradycardia, pauses and arrhythmia, wandering atrial pacemaker), conduction abnormalities (atrioventricular block grade I and grade II Mobitz 1) and repolarization abnormalities (early repolarization, T wave changes). The article gives a detailed description of ECG changes in the athlete's heart and in cardiovascular diseases responsible for most sudden cardiac deaths in young athletes.
