摘要
目的 明确左室纤维肌束的人群发生率。方法 连续选择 16 5 0例受试者 ,应用超声心动图多平面、多角度检测左室纤维肌束 ,对左室纤维肌束阳性率及位置构成比进行统计分析。结果 1311例左室纤维肌束阳性、共 15 12条。男女、有无心律失常之间左室纤维肌束的阳性率无统计学差异 (P >0 0 5 ) ;≥ 40岁组与 <40岁组的阳性率无统计学差异 (P >0 0 5 )。起于基部室间隔止于左室游离壁心尖段的左室纤维肌束占总条数的 83% (12 5 4/ 15 12 ) ,占总阳性例数的 96 %。结论 左室纤维肌束在人群中发生率极高 ,起于基部室间隔止于左室游离壁心尖段的左室纤维肌束有可能是左室腔内的一个正常解剖结构。
Objective To understand the prevalence of left ventricular fibromuscular band (LVFB) in human beingMethods Echocardiography was performed in consecutive 1650 cases of donors so as to find LVFBChi-Square Tests was introduced to comparing the rates of LVFB in groups according to age,sex,arrhythmias and no-arrhythmiasResults There were LVFB in 1311 cases (79%)There were no statistical difference whether between sex groups or in arrhythmias and no arrhythmia groups,≥40 yr and <40 yr groupsThe 96% of the LVFB were from the basal IVS to the apical of left ventricular free wall (LVFW)Conclusion The high rate of LVFB was observedThe LVFB from the basal IVS to the apical of LVFW might be a normal anatomic structure
