摘要 为评价民 VCG 和 ECG 对冠心病的诊断价值,观察50例冠脉及心室造影病人的 Q 及 T 向量改变,结果向量图和心电图对前壁心肌梗塞诊断符合率分别为92.3%和53.8%;下壁梗塞分别为81.8%和45.4%。侧壁梗塞均为33.3%;向量图对心肌缺血也有较高的敏感性(86.9%)及特异性(92.4%),并优于心电图;而且假阳性各组均较低。表明向量图在诊断心肌梗塞及心肌缺血方面,均有较好的诊断效能。 This article reports the detection of changes in Q and T vector of VCG in 50 cases with coronary arteri- ography and ventriculography.The results showed the diagnostic accuracy of VCG and ECG in anterior myocardial infarction was 92.3% and 53.8% respectively,posterior one was 81.8% and 45.4% respec- tively;and in lateral one both were 33. 3% respectively.The sensitivity and specificity of diagnosis for myocardial ischemia was 86.8% and 92.4% respectively,and that of VCG was superior to ECG.VCG has been proved to have better diagnostic effects on the diagnosis of myocardial infarction and ischemia.
