The Authors have evaluated the reliability of the most important electrocardiographic criteria for left ventricular hypertrophy in a group of 95 athletes. An ECG and a M- and B-mode echocardiogram have been performed in each subject; the criteria by Sokolow and Lyon, by Cornell, by Gubner, by Romhilt and Estes and by Casale have been employed to evaluate left ventricular hypertrophy. Left ventricular mass has been evaluated by the echocardiogram according to Devereux and coll. The electrocardiographic method by Casale and coll., proposed only for a few years, is based on the valuation of R wave and on the study of ventricular repolarization depending on sex and age. By this method, still now not much used in the study of athletes, a good correlation with the echocardiographic data was expected, in relation to the young age of the population. The athletes have been divided into three groups, practising aerobic sports, aerobic-anaerobic sports and power sports, according to the physiologic classification of the sports activities of Dal Monte. Using the chi-squared test, for the whole population and separately for the three groups, no significant statistical correlation has been observed. In conclusion, the results demonstrate that not only the "classic" criteria, but also the most recent ECG criteria of left ventricular hypertrophy are not reliable in evaluating left ventricular hypertrophy in trained athletes, leaving the final assessment of the real state of the cardiac chambers to echocardiography.
作者评估了95名运动员中左心室肥厚最重要的心电图标准的可靠性。对每位受试者进行了心电图检查以及M型和B型超声心动图检查；采用了索科洛和莱昂标准、康奈尔标准、古布纳标准、罗姆希尔特和埃斯蒂斯标准以及卡萨莱标准来评估左心室肥厚。根据德弗罗等人的方法，通过超声心动图评估左心室质量。卡萨莱等人提出的心电图方法仅出现数年，它基于R波的评估以及根据性别和年龄对心室复极的研究。鉴于该人群较为年轻，预计通过这种目前在运动员研究中使用不多的方法，能与超声心动图数据有良好的相关性。根据达尔蒙特对体育活动的生理分类，将运动员分为三组，分别从事有氧运动、有氧 - 无氧运动和力量运动。使用卡方检验，对全体人群以及分别对这三组进行分析，均未观察到显著的统计学相关性。总之，结果表明，不仅“经典”标准，而且最新的左心室肥厚心电图标准在评估训练有素的运动员的左心室肥厚时都不可靠，心脏腔室实际状况的最终评估仍需依靠超声心动图。
