Exercise cardiac imaging to study right ventricular functional remodelling in athletes with and without ventricular arrhythmias

极端运动导致心脏重塑，其长期后果尚不完全清楚。我们描述了耐力运动后心脏功能的短暂性下降。然而，我们也描述了一组有严重心律问题和持续右心脏异常的运动员。因此，我们假设极端运动可能会对一些运动员造成潜在的严重心脏变化，而在运动过程中进行详细的心脏评估可以预测那些风险最大的运动员。

Extreme exercise results in heart remodelling for which the long-term consequences are incompletely understood. We have described transient reductions in heart function following endurance sport. However, we have also described a group of athletes with serious heart rhythm problems and sustained right heart abnormalities. Therefore, we hypothesize that extreme exercise can cause potentially serious heart changes in some athletes and that detailed heart assessment during exercise will predict those at greatest risk.
