摘　　要：目的探讨体表心电图与心肌梗死罪犯血管的关系。方法比较急性心肌梗死患者心电图表现和选择性冠状动脉造影结果,进行统计和分析。结果下壁急性心肌梗死(acute miocardiol infarction,AMI)、下壁AMI伴右室AMI、新出现的房室传导阻滞、高侧壁导联ST段压低等其中的一项或几项者,其罪犯血管常为右冠状动脉;前侧壁、前间壁、前壁、广泛前壁AMI不伴或伴有下壁AMI、Ⅱ+Ⅲ+avF导联ST段压低中的一项,则其罪犯血管常为左前降支;后壁AMI不伴或伴有前侧壁AMI的罪犯血管常为左回旋支。结论根据体表心电图的改变能够初步推测出大多数患者AMI的罪犯血管。Objective To investigate the relationship between electrocardiographic manifestation and culprit vessel in patients with acute myocardial infarction. Methods To analyse 42 cases of electrocardiograms and the results of CAG from patients with acute myocardial infarction. Results The culprit vessel is often Right Coronary Artery （RCA） in patients with acute inferior myocardial infarction（AIMI） and AIMI accompanying right ventricular myocardial infarction （RVMI） ,first degree-third degree A-V block or high lateral ST segment depress. The culprit vessel is often Left Anterior Descending Branch （LAD） in patients with anterolateral wall,anter-septal,anterlor wall,extensive anterior wall acute myocardial infarction accompanying or not AIMI,tbe ST segment in Ⅱ ＋Ⅲ ＋ avF leads depressing; and Left Circumflex Branch （LCX） often followed with posterior wall acute myocardial infarction with or without anterolateral wall acute myocardial infarction. Conclusions The culprit vessel in acute myocardial infarction can be inferred preliminarily in most patients according to surface electrocardiogram.
