目的探讨临床拟诊冠心病患者心电图改变与冠状动脉造影结果的关系及心电图在冠心病诊断中的价值。指导临床诊断和治疗,以避免误诊和漏诊。方法冠状动脉造影与心电图结果进行对比分析。结果56例中冠脉造影检查阳性46例,阳性率为82.1%;造影前心电图异常43例中有36例诊断为冠心病,心电图正常42例中有30例诊断冠心病;心电图诊断冠心病敏感度为65.1%,特异度为63.2%。结论仅凭心电图改变对冠心病的诊断价值有限,临床应注意结合患者的病史、一般状态、主诉、既往史等,必要时进行冠脉造影及其他辅助检查以避免误诊和漏诊。
Objective To investigate the relationship between electrocardiographic changes and coronary angiography in clinically diagnosed patients with coronary heart disease and the value of electrocardiogram in the diagnosis of coronary heart disease. Guide clinical diagnosis and treatment to avoid misdiagnosis and missed diagnosis. Methods Coronary angiography and ECG results were compared. Results Of the 56 cases, 46 were positive coronary angiography, the positive rate was 82.1%; 36 cases of abnormal ECG before angiography 36 cases were diagnosed as coronary heart disease, electrocardiogram in 42 cases, 30 cases diagnosed coronary heart disease; ECG diagnosis of coronary heart disease The degree was 65.1% and the specificity was 63.2%. Conclusions The diagnosis of coronary heart disease based on electrocardiogram changes is limited. Clinicians should pay attention to the history, general state, chief complaint and past history of the patients. Coronary angiography and other auxiliary examinations should be performed if necessary to avoid misdiagnosis and missed diagnosis.
