将19例做过主动脉狭窄手术和12例进行过心导管检查或施行过修补术的大型室间隔缺损患者的术前心电图,与21例正常对照组进行比较。超声心动图测值采用简化立方体公式(Cubed formula)计算左室心肌重量。结果显示,主动脉狭窄组左室后壁及间隔厚度和左室腔容量显著大于正常组。室间隔缺损组仅左室腔容量显著大于正常组。18例主
Preoperative electrocardiography was performed in 19 patients with aortic stenosis and 12 patients with large ventricular septal defect undergoing cardiac catheterization or repair, compared with 21 normal controls. Echocardiographic measurements Left ventricular mass was calculated using the Cubed formula. The results showed that aortic stenosis left ventricular posterior wall and septum thickness and left ventricular volume was significantly greater than the normal group. Ventricular septal defect only left ventricular volume was significantly larger than the normal group. 18 cases of the main
