BACKGROUND
T-wave morphology has been shown to be more sensitive than QT and QTc interval to describe repolarization abnormalities. The electrocardiogram (ECG) performed in athletes may manifest abnormalities, including repolarization alterations. The aim of this study was to investigate the characteristics of T-wave morphology features in athletes.
METHODS
Eighty male elite athletes, consisting of 40 Tour de France cyclists (age 27±5years), 40 soccer players (age 26±6years) and 40 healthy men (age 27±5years) were included.
RESULTS
Sinus bradycardia, left ventricular (LV) hypertrophy, incomplete right bundle branch block and early repolarization were documented in 25 %, 20%, 13% and 14% of athletes, respectively. ECG criteria for LV hypertrophy in 12-lead ECG were more common in cyclists (35%) than in soccer players (5%), P<0.0001. Cyclists and soccer players had significantly longer RR interval, and repolarization features than the control group.
CONCLUSIONS
T-wave morphology of athletes is different from non-athletes, depending of the sport. Decreased potassium current in cardiomyocytes associated with LVH may contribute to these changes.
背景
已证明T波形态在描述复极异常方面比QT和QTc间期更敏感。运动员进行的心电图（ECG）可能显示异常，包括复极改变。本研究的目的是调查运动员T波形态特征。
方法
纳入80名男性精英运动员，包括40名环法自行车运动员（年龄27±5岁）、40名足球运动员（年龄26±6岁）和40名健康男性（年龄27±5岁）。
结果
分别有25%、20%、13%和14%的运动员记录到窦性心动过缓、左心室（LV）肥厚、不完全性右束支传导阻滞和早期复极。12导联心电图中LV肥厚的心电图标准在自行车运动员（35%）中比足球运动员（5%）更常见，P<0.0001。自行车运动员和足球运动员的RR间期和复极特征明显长于对照组。
结论
运动员的T波形态与非运动员不同，取决于运动项目。与LVH相关的心肌细胞钾电流降低可能导致这些变化。
