急性下壁心肌梗死可由右冠状动脉（RCA）和左回旋支（LCX）闭塞引起，体表心电图上可引起全部或部分下壁梗死相关导联 ST 段抬高，同时伴有或不伴有邻近导联、胸前导联、后壁导联、右室导联等 ST 段的改变。临床上可从上述导联的 ST 段变化以及不同导联 ST 段变化的组合、流程来定位急性下壁心肌梗死的罪犯血管，有较高的敏感性与特异性。本文就利用体表心电图对急性下壁心肌梗死罪犯血管进行定位研究进展作一综述。“,”Acute inferior myocardial infarction could result from the occlusion of right coronary artery(RCA)and left circumflex artery(LCX).It may lead to ST segment elevation in all or parts of the inferior-wall-infarct-related leads in surface electrocardiogram(ECG),accompanied with ST seg-ment changes of adjacent leads,precordial leads,posterior wall leads,right ventricular leads or not.Clinically,it is highly sensitive and specific to locate the culprit vessel of acute inferior myocar-dial infarction through the changes of ST segment in the above leads,and its different combination and procedure.This paper reviews on the research advance of the culprit vessel location of acute in-ferior myocardial infarction via surface ECG.
