对35例获得性心脏病患者的二维超声心动图检查(TDE)测定左心室射血分数(EF)和容量的5种不同算法与标准的X光电影血管造影(Cine)和放射性核素心脏造影(RVG)测定EF和容量的方法进行了比较。虽然所有方法都呈正相关，但相关程度因使用的算法不同而不同。对于EF的测定，TDE算法(尤其是使用多个切面的算法)优于通常用于M型超声心动图的一维算法。最佳算法(改进的Simpson‘’S规则)与电影EF(r[相关系数]=0.78；参见[估计的标准误差]0.097)和RVG EF(r=0.75；参见0.087)有很好的相关性，以做出临床有用的估计。TDE容量也与电影的舒张末和收缩末期容量相关(r=0.84；n=70)，但与较大的SEE(43ml)相关，其优势小于一维容量估计。
Five different algorithms for determining left ventricular (LV) ejection fraction (EF) and volumes from 2-dimensional echocardiographic examination (TDE) were compared to standard methods for obtaining EF and volume from X-ray cineangiography (cine) and EF from radionuclide ventriculography (RVG) in 35 patients [with various acquired heart diseases]. Although all methods correlated positively, the degree of correlation varied with the algorithm used. For EF determination, TDE algorithms (especially those using multiple planes of section) were superior to unidimensional algorithms commonly used with M-mode echocardiography. The best algorithm (modified Simpson''s rule) correlated well with cine EF (r [correlation coefficient] = 0.78; SEE [standard error of the estimate] 0.097) and RVG EF (r = 0.75; SEE 0.087) to make clinically useful estimates. TDE volumes also correlated with cine end-diastolic and end-systolic volumes (r = 0.84; n = 70) but were associated with a large SEE (43 ml) and offered less advantage over unidimensional volume estimations. Quantitative application of TDE appears to be a useful noninvasive method of evaluating LVEF, but is not as useful for estimating LV volumes.
