Interpretation of electrocardiogram in an ultra-marathon athlete: a case report

Abstract

The electrocardiogram (ECG) of athletes, especially in those that are endurance-trained, frequently shows some alterations; however, abnormalities of athlete’s ECG may be an expression of an underlying heart disease, which carries a risk of sudden death during sport. It is important that ECG abnormalities are correctly distinguished. We report a case of an ultramarathon athlete who arrived in Emergency Department, after a 100 kilometres race, showing ECG alterations that required further investigations to rule out a cardiac disease. ECG trace showed anterior repolarization abnormalities with ST-segment elevation in V1 to V3 leads. He was admitted in the Cardiology Department and underwent a coronary study that was normal. A cardiac magnetic resonance was also performed. The final diagnosis was athlete’s heart.
