摘　　要：目的:探讨运动员左室假腱索与心律失常和左心功能的关系。方法:1、通过对广东省体育运动技术学院1743名运动员进行心脏B超检查,调查运动员左室假腱索发生情况;2、将发现左室假腱索的93例运动员(排除心肌炎、心肌病等心脏疾患)作为一组,在无左室假腱索运动员中随机选取93名作为另一组,行心电图和心脏彩色多普勒检查,对比两组运动员心律失常和左心功能。结果:1743名无器质性心脏病运动员中,检测出93例左室假腱索,检出率为5.3%;其中Ⅰ型(横型)91例,Ⅱ型(纵型)2例。男、女运动员左心室假腱索发生率无明显差异。左心室假腱索运动员室性早搏发生率为74.19%,左心室无假腱索运动员室性早搏发生率为4.30%,二组差异有统计学意义(P<0.001);有、无左心室假腱索运动员左心功能指标之间无明显差异。结论:运动员左室假腱索与室性早搏明显相关。左室假腱索对运动员左心功能无明显影响。Objective To explore the relation of left ventricular false tendon（LVFT） to the cardiac arrhythmia and left ventricular function in athletes.Methods 93 athletes with LVFT were found in 1743 athletes at Guangdong Sports Technique Institute by B-type ultrasonic examination.They were assigned as the experimental group（exclusion of myocarditis and cardiomyopathy） and 93 matched normal athletes were randomly selected as the control group.Electrocardiogram and cardiac color doppler test were carried out to compare the incidence of cardiac arrhythmia and abnormal heart function in both groups.Results（1） The incidence of LVFT in this study was 5.3%（93/1743）,including 91 cases of Type I（horizontal type） and 2 cases of Type II（vertical type）without obvious gender difference.Organic heart diseases were excluded in these athletes with LVFT.Premature ventricular beats were found in 69 subjects（74.19%） in the experimental group and 4 subjects（4.30%） in the control（P 0.001）.There is no obvious difference in heart function between two groups.Conclusion LVFT in athletes strongly relates to the premature ventricular beats without abnormal heart function.
