Abstract
Objective：To discuss the judgements of Correlative coronary's infarct related arteries of acute Inferior myocardial infarction's ECG as well as the consolidation of right ventricle's infarction.
Methods：To comparative analyze the relation of ECGⅡ、Ⅲ Lead ST segment's raising proportionality of 95 cases with acute inferior myocardial infarction when hospitalized and the correlative infarct related arterises with I、avL lead ST segment excursion as well as coronary arteriography infarction.
Result：Among the 95 patients, 74 cases of ST Segment raise Ⅲ/Ⅱ＜1，＜1 causedby right coronary artery's blockage were respectively 70 cases and 4 cases; I, aVL lead ST segment raise isopotential line were 4 cases 70 cases were hypopiesis（P＜0.05＝. While 21 cases of ST segment raiseⅢ/Ⅱ＞1、＜I caused by levorotatory branch blockage were respectively 4 cases and 17 cases, 17 cases of I, aVL lead ST segment raise or isopotiential line ,4 cases of hypopiesis (P＜0.05＝.Among the 13 cases of consolidation right ventricle infarction, 11 cases were ventriculus dexter cordis judged byⅢ/Ⅱ＞1 （P＜0.05＝Conclusion The correlative infarct related arteries with acute inferior myocardial infarction are mostly RCA pathological process only a small part is LCX pathclogical precess. I、aVL lead raise or isopotential line is constantly observed in LCX pathological process，therefore I、aVL lead ST segment hypopiesis is highly valued in diagnosing right coronary artery's blackage. The difference of acute inferior ventricle judged by ST segmentⅢ/Ⅱ＞1 has a statistical significance.

临床上除了症状和血清心肌标记物生化指标外，心电图是诊断急性心肌梗死最常用最简便的措施。随着近年来冠脉介入治疗的广泛开展，梗死的心电图改变和相关罪犯血管的关系逐渐被人们熟知。用心电图ST段改变，早期判断急性下壁心肌梗死相关罪犯血管更具重要意义。近年来，一些学者对此提出不同的心电图诊断标准。但尚未得到公认。本文探讨心电图Ⅱ、Ⅲ导联ST段抬高比值和Ⅰ、aVL导联位移对急性下壁心肌梗死相关罪犯血管的价值以及是否合并右室梗死。 |
