The prevalence and clinical importance of false tendons were studied in 488 consecutive patients referred for echocardiography. Two hundred and eighty three (58%) patients had acquired heart disease, 91 (19%) had congenital heart disease, and 114 (23%) had normal hearts. Sixty six patients with normal hearts had innocent systolic murmurs and one had recurrent ventricular tachycardia. The overall prevalence of false tendons was 25% compared with 1.6% in a retrospective analysis of 763 cross sectional echocardiograms. When patients with innocent murmurs were excluded from statistical analysis, there was no significant difference in the prevalence of these tendons between children and adults, boys and girls, men and women, or between patients with acquired or congenital heart disease and normal patients. The prevalence of false tendons in patients with dilated left ventricles (57%), however, resembled that seen in necropsy studies. The prevalence of false tendons in patients with an innocent systolic murmur was 76% in children and 40% in adults, with an overall prevalence of 52%. False tendons are a common echocardiographic finding of no clinical importance except for their possible role in the genesis of innocent murmurs and ventricular arrhythmias. The echocardiographic detection of false tendons increases considerably when these structures are specifically sought and in conditions that result in left ventricular chamber dilatation.
对488例连续接受超声心动图检查的患者研究了假腱索的发生率及其临床意义。283例（58%）患者患有后天性心脏病，91例（19%）患有先天性心脏病，114例（23%）心脏正常。114例心脏正常的患者有生理性收缩期杂音，1例有复发性室性心动过速。假腱索的总体发生率为25%，而对763份横断面超声心动图进行回顾性分析时其发生率为1.6%。当将有生理性杂音的患者排除在统计分析之外时，儿童与成人、男孩与女孩、男性与女性之间，或后天性或先天性心脏病患者与心脏正常患者之间，这些腱索的发生率没有显著差异。然而，左心室扩大患者中假腱索的发生率（57%）与尸检研究所见相似。有生理性收缩期杂音患者中，儿童假腱索的发生率为76%，成人为40%，总体发生率为52%。假腱索是超声心动图常见的表现，除了可能在生理性杂音和室性心律失常的发生中起作用外，没有临床意义。当特意寻找这些结构以及在导致左心室腔扩大的情况下，超声心动图对假腱索的检出率会显著增加。
