左室假腱索(简称LVFT)可能为小儿心律失常或产生杂音的原因之一。为探讨其临床意义,现将1994年1月一1996年1月我们经超声心动检查确诊的22例报告如下。临床资料一、一般资料本组22例中男13例,女9例;年龄1,5~13岁,平均7．6岁。13例胸骨左缘3~4肋间有I级收缩期杂音,1例Ⅲ~Ⅳ级收缩期杂音且伴有收缩期震颤;8例有室性早搏,2例为偶发,6例频发早搏中有2例呈二联律;2例有家族史,其中1例父、母均有LVFT,且心脏均可闻及Ⅱ级收缩期杂音。另l例母亲有LVFT,自幼出现频发室早,有时呈二联律,多年早搏不消失。
Left ventricular false tendons (LVFT) may be one of the causes of arrhythmia or murmur in children. To explore its clinical significance, we now January January 1996 January our echocardiography confirmed 22 cases reported below. Clinical data First, the general information The group of 22 patients, 13 males and 9 females; aged 1,5 to 13 years, mean 7.6 years. Thirteen patients had grade I systolic murmur in the intercostal space of 3 to 4 at the left margin of the sternum, 1 systolic murmur with grade Ⅲ-Ⅳ systolic murmur accompanied by systolic tremor, 8 patients with premature ventricular contractions, 2 incidental and 6 frequent premature beats There were 2 cases in the second law; 2 cases had a family history, of which 1 case of father and mother were LVFT, and the heart can be heard and Ⅱ grade systolic murmur. The other l cases of mothers have LVFT, early occurrence of frequent room early, and sometimes showed a couplet law, years of premature beats disappeared.
