摘　　要：近一年来连续二维超声心动图受检的2134例中,检出LVFT241例,检出率11.29％。≥60岁者为老年组共461名,检出LVFT 46例(9.98％),<60岁者为非老年组共1637名,检出LVFT195例(11.66％),二组无显著差异(P>0.05),提示LVFT并不随年龄增长而增加。男女检出率亦无差异。两组LVFT均以长纵型最多见:一般一条,少数2～3条。两组合并SM_(Ⅰ-Ⅱ)(still杂音)分别为97.83％和96.41％;杂音的产生与LVFT受血流冲击震颤有关。LVFT合并心律失常占26.56％,两组无显著差异,但老年组严重心律失常远较非老年组为多;提示老年人LVFT致心律失常的严重性。FT内存在有浦肯野细胞,加之心室舒缩时对LVFT的牵张,故认为LVFT是心律失常的病源因素。In I993 (from January to December) , 24I cases of left ventricular false tendons (LVFT) ,rated II. 29% were confirmed by 2 -dimensional echocardiograms of 2I34 cases;9.98% and II. 66% were found in the aged group and nonaged group respectively. No significant difference was revealed in the two groups (P>0. 05). It suggests that LVFT doesn't go up along with the advancing of the age. Most of the LVFT cases were of longitudinal type (over 80%)with one tendon and a few with 2 - 3 tendons. In the two groups , pre-cardial SMⅠ-Ⅱ, (still's murmur)were 97. 83% and 96. 4I%respectively. It's related to the tremor of the false tendon 26. 56% were associated with arrhythmia in the aged group. Although there was no marked difference in the two groups ,arrhythmia was more serious with the aged group. It suggests that the seriousness of arrhythmia with the age might be related to the Purkinje's cell in the false tendon and the stretch on LVFT byventricular diastole and systole and so the authors think that FT is the etiogical factor of arrhythmia.
