分析12导联心电图对冠心病心肌缺血的监测价值

目的分析12导联心电图对冠心病心肌缺血的监测价值。方法选取2017年5月至2019年4月我院接诊的老年冠心病患者90例为研究对象,均行12导联心电图与常规心电图检查,比较两种检查方法对冠心病检出率、检出部位及对心肌缺血检出率,分析两种方法对冠心病心肌缺血的监测价值。结果12导联心电图对冠心病检出率高于常规心电图(P<0.05),12导联心电图对下壁、侧壁的检出率高于常规心电图,且12导联心电图对ST段抬高、ST段压低的检出率也高于常规心电图(P<0.05);12导联心电图诊断冠心病心肌缺血的灵敏度明显高于常规心电图(P<0.05),两者诊断特异度、准确度比较差异无统计学意义(P>0.05)。结论12导联心电图用于冠心病心肌缺血的诊断中有较高价值,可较好检出心肌缺血及缺血部位,值得广泛应用。

Analysis on Monitoring Value of 12-leads Electrocardiogram for Myocardial Ischemia of Coronary Heart Disease

Objective To analyze the monitoring value of 12-leads electrocardiogram(ECG)for myocardial ischemia of coronary heart disease(CHD).Methods A total of 90 elderly CHD patients who were treated in the hospital from May 2017 to April 2019 were enrolled.All patients underwent 12-lead ECG and routine ECG examination.The detection rate of CHD,detection sites and detection rate of myocardial ischemia were compared between the two groups.The monitoring value of the two methods for myocardial ischemia of CHD was analyzed.Results The detection rate of 12-lead ECG was higher than that of routine ECG for CHD(P<0.05).The detection rates of 12-lead ECG for lower wall and sidewall were higher than those of routine ECG.The detection rates of 12-lead ECG for ST-segment elevation and ST-segment depression were higher than those of routine ECG(P<0.05).The sensitivity of 12-lead ECG for diagnosis of myocardial ischemia of CHD was significantly higher than that of routine ECG(P>0.05).There was no significant difference in diagnostic specificity or accuracy between the two methods(P>0.05).Conclusion The diagnostic value of 12-lead ECG is relatively high for myocardial ischemia of CHD.It can well detect myocardial ischemia and ischemic sites.
