In the past myocarditis has been suggested as a possible cause of repolarization abnormalities in sportsmen, but, to our knowledge, no direct in-vivo demonstration of this relationship has so far been found. We report the cases of three professional athletes with repolarization changes at rest and/or during exercise and mild segmental wall motion anomalies in the left ventricle on echocardiography, in whom myocarditis was diagnosed by non-invasive and invasive clinical investigations, including endomyocardial biopsy. We think that probably the frequency with which myocarditis is responsible for electrocardiographic and echocardiographic abnormalities in athletes has so far been underestimated, and that caution must be employed when interpreting minor segmental wall motion abnormalities on resting and exercise echocardiograms in trained subjects as being due to athlete's hart, especially when they present with repolarization changes.
过去曾有人提出心肌炎可能是运动员复极异常的一个潜在原因，但据我们所知，目前尚未发现这种关系的直接体内证据。我们报告了三例职业运动员的病例，他们在静息和/或运动时出现复极改变，超声心动图显示左心室有轻度节段性室壁运动异常，通过包括心内膜心肌活检在内的非侵入性和侵入性临床检查诊断为心肌炎。我们认为，迄今为止，心肌炎导致运动员心电图和超声心动图异常的发生率可能被低估了，在将训练有素的受试者静息和运动时超声心动图上的轻度节段性室壁运动异常解释为运动员心脏时必须谨慎，尤其是当他们伴有复极改变时。
