不稳定型心绞痛心电图诊断

Electrocardiogram Diagnosis of Unstable Angina Pectoris

目的 探讨不稳定型心绞痛患者心电图及动态心电图表现。方法 选取2012年-2013年收治的不稳定型心绞痛患者心电图诊断资料进行分析。结果 心绞痛发作时可出现暂时性心肌缺血引起的ST段压低（≥0.1 mV）。心电图负荷实验及24 h动态心电图可显著提高缺血性心脏病的检出率。结论 心电图检查是发现心肌缺血、诊断心绞痛最常用的检查方法。

Objective The electrocardiogram and dynamic electrocardiogram of the patients with the unstable angina pectois are to be investigated. Methods Electrocardiogram diagnosis data of patients with angina pectoris in this hospital from 2012 to 2013 are selected for analysis.Results Whwen the angina pectoris happers,ST segment depression（ ≥ 0.1 mV ） can be calsed by transient myocardial ischemia,Electrocardiogram stress test and 24h dynamic electrocardiogram can significantly improve the detection rate ofischemic heart disease. Conclusion Electrocardiogram examination is the most widely used inspection method to detect the myocardial ischemia and diagnose the angina pectoris.
