“运动员心脏综合征”系竞技状态良好者心脏对长期运动的一种生理性适应。运动员心电图常呈现窦性心律缓慢,Ⅰ度房室阻滞,右或左室肥厚及酷似心肌缺血图形。为确定以体力训练为主的运动员心电图改变及其与体型或种族之关系,本文对289例外观健康的男性职业足球运动员作了详细的心电图分析。方法:对1976～1981年间303例年龄21～35岁的职业运动员作了临床与心电图检查。14例因各种疾病而予剔除,所余289例均测定了身高、体重、体表面积及血压。凡12导联心电图上呈现复极 “Athlete’s Heart Syndrome” is a physiological adaptation of the heart to long-term exercise in a well-exercised state. Athletes ECG often presents slow sinus rhythm, Ⅰ degree atrioventricular block, right or left ventricular hypertrophy and myocardial ischemia similar to the pattern. In order to determine the changes of electrocardiogram (ECG) of athletes mainly based on physical training and their relationship with body shape or race, this article made a detailed ECG analysis on 289 healthy male professional football players. Methods: The clinical and electrocardiographic examinations of 303 athletes aged 21-35 years from 1976 to 1981 were conducted. 14 cases were excluded due to various diseases, the remaining 289 cases were measured height, weight, body surface area and blood pressure. Where 12 lead electrocardiogram showed repolarization
