冠心病43例包括急性心肌梗塞(AMI)和陈旧性心肌梗塞(OMI)各10例,心绞痛(AG)23例,与64例正常人体表晚电位的对照中发现:(1)AMI和AG病人异常的FQRSd、RMS_(40)和LPd与正常人之间具有显著的差异(P<0.001),OMI病人仅FQRSd与正常人间具有显著性差异(P<0.001);(2)AMI和AG病人晚电位的敏感度分别为30％和43.5％,准确度分别为90.5％和85.1％,特异度均为100％,无合并症的OMI病人记录晚电位无临床意义;(3)冠心病的晚电位与心脏增大和心功能不全有关,与血总胆固醇浓度的关系尚待进一步研究。
Coronary heart disease in 43 cases, including 10 cases of acute myocardial infarction (AMI) and old myocardial infarction (OMI), 23 cases of angina pectoris (AG), and 64 normal subjects were found in late phase potentials: (1) AMI and AG patients The abnormal FQRSd, RMS_ (40) and LPd had significant difference (P <0.001) compared with normal subjects, and there was significant difference between OQI and normal subjects only (P <0.001) The sensitivity of the potential were 30% and 43.5%, the accuracy was 90.5% and 85.1%, respectively, the specificity of 100%, no complication of OMI patients recorded late potential no clinical significance; (3) late potential of coronary heart disease With the increase of heart and cardiac insufficiency, and the relationship between blood total cholesterol remains to be further studied.
