An attempt was made to reveal the possible relationship between ECG changes and the isotonic type of myocardial hyperfunction observed in sportsmen training to develop their endurance. Two groups of sportsmen were studied. Group 1 included 45 sportsmen of a high qualification developing their endurance. Group 2 consisted of control sportsmen with other trends in their training. The obtained results demonstrated that Group 1 sportsmen developed a significantly higher incidence of partial right bundle branch block and syndrome of delayed excitation of the right supraventricular crest, than Group 2 sportsmen. They also had a significantly higher amplitude of Q, R and T-waves and local electronegative period in the left thoracic leads. This permitted to conclude that the isotonic type of hyperfunction of the right or left ventricles in sportsmen training for higher endurance is reflected in their ECG.
研究人员试图揭示心电图变化与耐力训练运动员中观察到的等张型心肌功能亢进之间的可能关系。研究了两组运动员。第一组包括45名高水平的耐力训练运动员。第二组由训练有其他倾向的对照运动员组成。所得结果表明，第一组运动员出现不完全性右束支传导阻滞和右室上嵴延迟激动综合征的发生率显著高于第二组运动员。他们在左胸导联的Q、R和T波振幅以及局部电负期也显著更高。由此可以得出结论，耐力训练运动员右心室或左心室等张型功能亢进在其心电图中有所体现。
