High-level physical training induces cardiac structural and functional changes, including 12-lead electrocardiogram modifications.
The purpose of this cross-sectional longitudinal study was to establish a quantitative electrocardiographic profile in highly trained football players. Initial and serial annual electrocardiogram monitoring over subsequent years allowed us to investigate the long-term effects of exercise on cardiac conduction and electrophysiological remodelling.
Between 2005 and 2015, serial evaluations, including 12-lead electrocardiograms, were performed in 2484 elite male football players from the French Professional Football League. A total of 6247 electrocardiograms were performed (mean 2.5±1.8 electrocardiograms/player). Heart rate (beats/min), atrioventricular delay (PR, ms), intraventricular conduction delay (QRS, ms), corrected QT delay (QTc) and electrical left ventricular hypertrophy (LVH) (Sokolow-Lyon index, mm) were measured, and the fixed effect of time was evaluated using panel data analysis (β [95% confidence interval] change between two visits).
According to European Society of Cardiology and Seattle criteria, 15% of the electrocardiogram intervals were considered abnormal. We observed 17% sinus bradycardia<50 beats/min (mean heart rate 60±11 beats/min), 8% first-degree atrioventricular block>200ms (mean PR 170±27ms), 1.5% QRS>120ms (mean QRS 87±19ms) and 3% prolonged QT interval (mean QTc using Bazett's formula [QTcB] 395±42ms). Electrical LVH (mean Sokolow-Lyon index 34±10mm) was noted in 37% of players. Over time, electrocardiogram changes were noted, with a significant remodelling trend in terms of decreased heart rate (-0.41 [-0.55 to -0.26] beats/min), QRS duration (-2.4 [-2.7 to -2.1] ms) and QTcB delay (-1.2 [-1.9 to -0.5] ms) (all P<0.001).
This study describes usual electrocardiographic training-induced changes in a large series of football players over the follow-up timeframe. The most frequent outliers were electrical LVH and sinus bradycardia. These results have important implications for optimizing electrocardiogram interval measurements in initial screening and during follow-up of football players, with potential cost-effective implications.
高水平的体能训练会引起心脏结构和功能的变化,包括 12 导联心电图的改变。
本横断面纵向研究的目的是建立一个在高度训练的足球运动员中的定量心电图图谱。对随后几年的初始和连续年度心电图监测,使我们能够研究运动对心脏传导和电生理重塑的长期影响。
在 2005 年至 2015 年间,对来自法国职业足球联赛的 2484 名精英男性足球运动员进行了一系列评估,包括 12 导联心电图。共进行了 6247 次心电图检查(平均每名运动员 2.5±1.8 次心电图)。测量心率(次/分钟)、房室延迟(PR 间期,ms)、室内传导延迟(QRS 间期,ms)、校正 QT 间期(QTc)和电左心室肥厚(LVH)(Sokolow-Lyon 指数,mm),并使用面板数据分析评估时间的固定效应(两次就诊之间的β[95%置信区间]变化)。
根据欧洲心脏病学会和西雅图标准,15%的心电图间隔被认为异常。我们观察到 17%的窦性心动过缓<50 次/分钟(平均心率 60±11 次/分钟),8%的一度房室传导阻滞>200ms(平均 PR 间期 170±27ms),1.5%的 QRS>120ms(平均 QRS 间期 87±19ms)和 3%的 QT 间期延长(使用 Bazett 公式的平均 QTc[QTcB]395±42ms)。37%的运动员出现电 LVH(平均 Sokolow-Lyon 指数 34±10mm)。随着时间的推移,心电图发生了变化,心率(-0.41[-0.55 至-0.26]次/分钟)、QRS 持续时间(-2.4[-2.7 至-2.1]ms)和 QTcB 延迟(-1.2[-1.9 至-0.5]ms)均有显著的重塑趋势(均 P<0.001)。
本研究描述了在足球运动员随访期间,一系列大型系列心电图训练诱导的常见变化。最常见的异常值是电 LVH 和窦性心动过缓。这些结果对于优化足球运动员初始筛查和随访期间的心电图间期测量具有重要意义,具有潜在的成本效益。
