多部位急性ST段抬高型心肌梗死的心电图与冠状动脉造影的对比分析

Comparative analyses of ECG and coronary angiography of acute ST elevation myocardial infarction of multiple location

[目的]探讨多部位急性ST段抬高型心肌梗死(STEMI)的体表心电图定位及其冠脉病变的特征。[方法]分析12例多部位急性STEMI患者的心电图特征及急诊冠脉造影结果,并加以对照比较。[结果]根据心电图判断IRA的准确性为100%,多部位急性STEMI患者的多支冠脉病变占83%。[结论]体表心电图可以准确判定IRA,多部位急性STEMI患者冠脉病变较为弥漫。

[ Objective]To discuss the ECG manifestations which related to anatomy of infarct- related artery （IRA） and coronary angiographic characteristics of acute ST elevation myocardial infarction （STEMI） of multiple location. [ Methods ] Analyses the ECG features and coronary angiographic results of 12 cases of acute STEMI of multiple location. [Results] The predictive accuracy of IRA by ECG was 100%, there were 83% multiple coronary diseases in which the patients had acute STEMI of multiple location. [ Conclusion] The anatomical data of IRA can be acquired accurately by analyzing ECG, the coronary lesions of acute STEMI of multiple location were more extensive and severe.
