摘要
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。
The ventricular late potentials (VLP) are determined on the body surface of 43 cases of coronary heart diseases including 10 of acute myocardial infarction (AMI), and 10 old myocardial infarction(OMI), and 23 of angina pectoris(AG). 64 normal subjects are also examined to serve as control. As the parameters of the cases of AMI and AG are compared with those of the control, the dif-fererence of the filtered QRS duration is 20%, 26% vs 0% (P<0.001) , of the root mean square voltage of the signs in the terminal 40 ms of the FQRS (RMS 40) is 40% and 56% vs 5% (P<0.001) , and of the late potential duration (LPd) is 30%, 44% vs 0% (P<0.001) It is believed that VLP is closely related to the cardiac size and cardiac functions and VLP determinantion is of paramount important in the management of patients with AMI and AG.
