摘　　要：目的研究AVR导联上ST段的压低在预测下壁ST段抬高型心肌梗死（STEMI）的罪犯血管中的作用。方法选择行急诊血管造影术的急性下壁ST段抬高型心肌梗死患者106例，分析其心电图特点与血管造影结果之间的关系，应用AVR导联上ST段压低预测下壁STEMI的罪犯血管为左回旋支（LCX），分析该研究人群中下壁梗死的罪犯血管。评价AVR导联上ST段压低预测罪犯血管的灵敏性及特异度。结果AVR导联上ST段压低预测罪犯血管为左回旋支的灵敏度及特异性分别为53％、86％。预测右冠状动脉（RCA）为罪犯血管的灵敏度和特异性分别为86％、55％。结论AVR导联上ST段压低是一种预测下壁ST段抬高型心肌梗死的简单方法。Objective To investigate the effect of ST depression in lead AVR on predicting the culprit artery in inferior ST- segment elevation myocardial infarction（STEMI）. Methods One hundred and six patients with acute inferior STEMI underwent emergent coronary angiography were choosed, the relationship between electrocardiographic characteristics and angiographic findings was an.alyzed. ST depression in AVR was used for predicting the left circumflex artery （LCX） as the culprit to the population. Finally, the sensitivities and specificities of the ST depression in lead AVR for predicting the culprit artery were evaluated. Results The sensitivity and specificity of ST depression in lead AVR to predict LCX as the culprit were 53% and 86%, respectively; 86% and 55% for predicting the right coronary artery （RCA） as the culprit. Conclusions ST depression in AVR is a simple method to pre, dict the culprit artery in inferior STEMI.
