高频心电图对冠心病的判别作用研究

为探讨高频心电图对冠心病的判别作用，采用Ｂａｙｅｓ方法分析９３例冠心病率患者和７７例正常人体表１２导联的高频切迹。结果显示：除Ｉ和Ｖ２导联外，其余１０个导联的高频切迹对冠心病和正常人具有明显的判别作用。

Discriminant analysis of high frequency electrocardiogram for coronary heart disease

Adopting Bayes discriminant analysis, authors studied high frequency notching (HFN) of body surface, 12 leads in 93 cases of coronary heart disease (CHD)and 77 healthy subjects in order to in-vestigate discriminant effect of HFN on CHD. Results showed that HFN of 10 leads had significant discriminant effects except for I and V2 leads among 12 leads by stepwise discriminant analysis (P<0.01) . Meanwhile,we established two discriminant functions of CHD and healthy subjects by meams of 10 leads , introducedwith sig-nificantlydiscriminant ability for CHD and normal group(P < 0.01)Coincidence rate, sensitivity and specificity of either internal or external determination came high up to 88.82%, 89.25%, 88.31%and 84.11%, 83.87%, 84.42%, respectively.These results suggest that HFECG possessed significant discriminant ability for CHD,and it could play an important role in early diagnose of CHD.
