【摘要】 本文报道应用二维超声心动图(2DE)在1264例中检出50例左室条束。检出率为3.96％,与Vered等报告的2～4％相近。诊断标准为:不论任何一个切面,凡有跨越左室腔的线样回声,且与二尖瓣叶不相连者即可确定。鉴于左室条束起止多变,因此著者认为多切面检查至为重要。左室长轴切面发现率最高,最易发现室间隔至心尖部或乳头肌的条束;二尖瓣及乳头肌水平短轴切面次之、较易发现室间隔至前或侧壁之条束;心尖四腔切面发现率较少、易发现近心尖部细小的或网络样条束回声。本文还就条束患者的临床资料进行了分析、对鉴别诊断等问题提供了初步看法,更多还原

【Abstract】 A serie of 50 cases of left ventricular bands detected by 2-dimensional echocardiography(2-DE)in 1264 consecutive subjects was reported.The identified rate(3.96%)was similar to that of Vered et al(2-4%).The diagnostic criteria of the left ventricular bands were of some any linear echo with dense structures crossing the left ventricular cavity,but not attaching to the mitral valve on any section.It was found that the starting and terminal inserted point of the left ventricular bands were quite various,so,it is suggested that to examine the patient with multiple section views is very important.The bands inserted from septum to apex were most frequently and easily to be detected in the left ventricular long axis view.Those from septum to free wall were more frequently and easily to be detected in the short axis view at the level of mitral valve or of papillary muscle.In few cases,those near apex or assumed some small networks were detected in the apical four chamber view.In addition,the clinical data have been analysed,and the clinical significance of the left ventricular bands has been discussed.更多还原
