摘要
目的在心肌梗死患者中,观察心电图改变与梗死相关冠脉(IRA)病变之间的相关性。方法51例入选分析。所有病例均接受冠脉造影。结果以左前降支(LAD)为梗死相关冠脉(IRA),单次梗死者,最常累及的导联是V2导联,无论单支病变还是双支和三支病变,部分病例都累及右胸导联和下壁导联;以右冠(RCA)或左回旋支(LCX)为IRA,均可累及下壁和右胸导联,但LCX可累及高侧壁或侧壁。结论在心肌梗死患者中,分析常规12导联心电图,有助对冠脉病变的推测,在此基础上加选用导联,能更精确推测冠脉病变。
Objective Observation the relationship between electrocardiogram and infarct -related artery(IRA)lesion in patients with myocardial infarction.Methods 51patients were enrolled.All patients underwent angiography.Results In patients with LAD as IRA,the most common change in electrocardiogram located in lead V 2 .No matter single -vessel,tow -vessel or three -vessel lesion,the electrocardiographic changes could extend to right chest leads and inferior leads in some patients with LAD as IRA.Both in patients with RCA as IRA and with LCX as IRA,the electrocardiographic changes could extend to righe chest leads and inferior leads.But in patients with LCX as IRA,the electrocardiographic changes could extend to high lateral and lateral leads.Conclusion Observation to the routine12-lead electrocardiogram was helpful in prediction the coronary artery lesion in patients with myocardial infarction.Using some additional leads could further improve the prediction of coronary artery lesion.[
