摘要 我们在同一病例组上对两个计算机诊断系统的诊断价值进行了比较。两个系统中,一个完成对心电图的解释,另一个完成对心向量图和重建心向量图的解释。病例组总数为2625例,其中正常人1065例,左心室肥大216例,右心室肥大34例,双心室肥大23例,前壁心梗340例,下壁心梗700例,复合心梗247例。结果显示,重建心向量图具有与常规心向量图类似的诊断精度,将这个由心电图推算而来的诊断与心电图并用,可以提高心电图对正常、左心室肥大以及复合心梗的诊断正确率。提示重建心向量图在多种疾病的诊断中具有一定价值,存在于常规心向量图中的诊断信息也存在于同步记录的心电图中,对后者的利用可以提高心电图的诊断价值。 The diagnostic values of two computer interpretation systems, one for ECG, the other for VCG and VCG reconstructed from 12 lead of ECG (VCGr), on one set of data base were compared. THe data base composed of 2 625 cases, including 1065 healthy persons (NSA), 216 cases of left ventricular hypertrophy (LVH), 34 cases of right ventricular hypertrophy (RVH), 23 cases of biventricular hypertriphy (BVH), 340 cases of anterior myocardial infarction (AMI), 700 cases of inferior myocardial infarction (IMI) and 247 cases of mixed infarction (MIX). The results showed that except for IMI and MIX, VCGr was nearly the same as VCG in diagnostic accuracy, and the combined use of ECG and VCGr, which was simply a reconstruction from ECG, gave more diagnostic values in NSA, LVH and MIX than ECG only. These indicate that VCGr is valuable in most cases, and diagnostic information in the oringinal VCG is also present in the simultaneous recorded 12 lead ECG which could improve the diagnostic significance of ECG.
