摘　　要：目的探讨小儿左心室假腱索(leftventricularfalsetendonsin,LVFT)的超声心动图特征及临床意义。方法对小儿LVFT54例给以心动图超声分型,分析其对应的临床表现。结果本组LVFT发生率45%,呈线状,分纵向型及横向型。引起Ⅰ～Ⅱ级杂音发生率29%,横向型多于纵向型。引起异常心电图发生率48%,纵向型多于横向型。结论LVFT应首选超声心动图检查。LVFT可引起生理性杂音及心电图异常,与室间隔近90°者可引起早期复极综合征。Objectives To investigate the echocardiogram character and clinical significance of left ventricular false tendons （LVFT） in children. Methods 54 cases with LEVT in children was classified according to echocardiogram, and corresponding clinical significance was analyzed. Results The incidence of LVFT was 44.63 % presented as thread shapes. It fall into longitudinal type and transverse type. The incidence of Ⅰ -Ⅱ grade of murmur was 29.2%. That of transverse type was higher than that of longitudinal type. The incidence of abnormal electrocardiogram was 48.14%, that of longitudinal type was higher than that of transverse type. Conclusions Echocardiography should be the first choice for diagnosing LVFT. It could cause physiological murmur and abnormal electrocardiogram. LVFT in the higher position could cause Ⅲ degree of murmur. That of perpendicular to the ventricular septum could cause early repolarization svndrome.
