QT interval and QT dispersion in endurance athletes and in power athletes using large doses of anabolic steroids
(QT-Intervall und QT-Dispersion bei Ausdauer- und Kraftsportlern, die hohe Dosen anaboler Steroide nehmen)
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.
