目的：探讨急性下壁心肌梗死心电图改变与梗死相关血管的相关性。方法：选取2007年1月-2014年5月本院收治的急性下壁心肌梗死（IAIM）患者60例，对所有患者心电图资料进行回顾性分析，并与冠脉造影资料进行比较，分析两者相关性。结果：心电图ST段抬高Ⅲ>Ⅱ中，RCA病变占84.0%，明显大于LCX病变（P<0.05）；心电图ST段压低AVL>I中，RCA病变占86.8%，明显大于LCX病变（P<0.05）；V3导联ST段压低与Ⅲ导联ST段抬高比值>1.2中，RCA病变占18.2%，明显小于LCX病变（P<0.05）；心电图AVL S/R>1/3伴ST段压低>1 mm，RCA病变占84.0%，明显大于LCX病变（P<0.05）；V3导联ST段压低与Ⅲ导联ST段抬高比值>1.2时，LCX病变占77.8%，明显大于RCA病变不同部位闭塞所占比例（P<0.05）；在0.5~1.2之间时， RCA病变远端闭塞占75.0%，明显大于RCA近中段闭塞和LCX闭塞病变组（P<0.05）；<0.5时RCA近中段闭塞共占87.5%，明显大于其他两个位置（P<0.05）。结论：IAIM患者心电图显示与梗死相关动脉具有明显相关性，因此具有明显预测价值。

Objective:To study the correlation of the electrocardiogram(ECG)changes of acute inferior wall myocardial infarction associated with infarction blood vessels.Method:60 cases of acute inferior wall myocardial infarction (IAIM)from January 2007 to May 2014 in our hospital were selected. All ECG data of patients were retrospectively analyzed,and compared with coronary angiography data to analyze the correlation.Result:In the ECG ST segment elevationⅢ>Ⅱ,the RCA group accounted for 84.0%,was significantly greater than the LCX group(P<0.05);in the ECG ST segment lower AVL>I,RCA group accounted for 86.8%,was significantly greater than the LCX group(P<0.05);lead the V3 ST segment lower and leadⅢst-elevation ratio>1.2,the RCA group accounted for 18.2%,was significantly less than the LCX group(P<0.05);ECG AVL S/R>1/3 with ST segment lower>1 mm,the RCA group accounted for 84.0%,was significantly greater than the LCX group(P<0.05);V3 lead ST segment lower and leadⅢst-elevation ratio>1.2,the LCX lesions group accounted for 77.8%,was significantly greater than the proportion of the different parts of occlusion in the RCA group(P<0.05);between 0.5-1.2,RCA distal occlusion accounted for 75.0%,was significantly greater than RCA near the middle block and the LCX occlusion lesion group(P<0.05);<0.5 RCA near the middle block accounted for 87.5%,was significantly greater than the other two position(P<0.05).Conclusion:ECG IAIM display with infarct-related artery in patients with significant correlation,it has obvious predictive value.
