摘　　要：运用二维超声心动图和左室Ｘ线造影方法，评价９０例法乐氏四联症的左室容量和左室时血分数，各测值与年龄相匹配的４０例正常人对照。研究结果表明，二维超声心动图的Ｓｉｍｐｏｎ’ｓ和面积长度法的左室容量测值与左室Ｘ线造影面积长度法相应测值比较，它们之间呈高度相关，但二维超声的面积长度法测值较低于左室造影测值，法乐氏四联症患者的左室容量明显低于正常对照组，而左室射血分数与正常组对照无明显差异。结论，二维超声定量评价法乐氏四联症患者的左室容量时．以Ｓｉｍｐｓｏｎ’ｓ法更准确，面积长度法则轻度低估，术前法乐氏四联症患者的左室射血分数正常。For 90 patients with tetralogy of Fallot(TOF), two dimensional echocardiography(2DE)and angiocardiography were employed to measure the left ventricular volume (LVV)and left ventricular ejection fraction(LVEF). The results were compared with 40 normal volunteers with matched age. It showed that LVV and LVEF measured by 2DE-Simpson’s method and 2DE area-length method had good correlation with those by angiocardiography, but 2DE area-length method underestimated LVV compared with angiocardiography. The LVV in patients with TOF was significantly lower than that in normal subjects. However,there were no significant difference in LVEF, It concluded that LVV maesured by 2DE-Simpson’s method was more accurate than 2DE arealength method the later slightly underestimated the VV. Furthermore, LVEF in patients with TOF was normal.
