摘　　要：为探讨十二导联动态心电图对冠心病心肌缺血发作患者的诊断价值,选择2017年1月~2019年1月期间本院心内科住院部收治的冠心病患者80例,全部患者均实施常规心电图、十二导联动态心电图和冠脉造影检查,以此来分析不同检查方法对冠心病心肌缺血发作患者的诊断价值。十二导联动态心电图对冠心病心肌缺血发作的检出率、对侧壁及下壁心肌缺血的检出率均明显高于常规心电图,对冠心病心肌缺血发作次数的检出也明显多于常规心电图,差异具有显著性(P<0.05)。两种检查方法均发现多支冠脉病变患者的心肌缺血发作频率明显高于单支冠脉病变患者(P<0.05)。十二导联动态心电图对冠心病心肌缺血发作的诊断敏感性、阴性预测值和准确度明显高于常规心电图(P<0.05)。本研究证实,十二导联动态心电图可明显提高冠心病心肌缺血发作患者的检出率,改善诊断效能,明确心肌缺血发作次数和病变部位,可在临床推广应用。To investigate the diagnostic value of 12 lead dynamic electrocardiogram for myocardial ischemic attack in patients with coronary heart disease, 80 patients with coronary heart disease admitted to cardiology inpatient department of our hospital from January 2017 to January 2019 were selected. All patients were underwent routine electrocardiogram, 12 lead dynamic electrocardiogram and coronary angiography.The diagnostic value of different examinations for myocardial ischemic attack in patients with coronary heart disease were analyzed.The positive rate of myocardial ischemia attack in patients with coronary heart disease by 12 lead dynamic electrocardiogram was much higher than that of conventional electrocardiogram.And the positive rate of myocardial ischemia attack in lateral wall,inferior wall by 12 lead dynamic electrocardiogram was much higher than that of conventional electrocardiogram.And the frequency of myocardial ischemia attack in patients found by12 lead dynamic electrocardiogram was more than that of conventional electrocardiogram,P<0.05.Both methods showed that myocardial ischemic attack in patients with multi-vessel coronary artery disease was significantly higher than that in single-vessel coronary artery disease,P<0.05.The diagnostic sensitivity,negative predictive value and accuracy of 12 lead dynamic electrocardiogram for myocardial ischemic attack of coronary heart disease were significantly higher than that of conventional electrocardiogram,P<0.05.In conclusion,12 lead dynamic electrocardiogram is beneficial to improve the positive rate of myocardial ischemic attack in patients with coronary heart disease,improve the diagnostic efficiency,and clarify the frequency and the lesion site of myocardial ischemic attack,which is the worthy of clinical application.
