摘要：

We measured electrocardiographic repolarization indexes in athletes. Physiologic adaptive cardiac hypertrophy did not increase QT dispersion in endurance athletes despite long QT intervals due to increased vagal tone. In contrast, power athletes taking large doses of anabolic steroids had increased QT dispersion despite short QT intervals, which seems to reflect altered myocardium in the hypertrophied heart.
