Abstract

[Objective]To determine whether electrocardiogram obtained on admission could identify left circumflex(LCX) or right coronary artery(RAC) occlusion as the cause of an acute inferior myocardial infarction(AIMI).[Methods]In this study,432 patients were included.For continuous variables,the statistical significance of differences between groups was analyzed by unpaired Students t test.The chi-square test was used to compare differences between discrete variables.[Results]STⅢ↑STⅡ↑ means the RCA as the IRA Se 87.80%,Sp 92.31%,STaVL↓≥0.1 mV and SaVL/ RaVL1/3 means the RCA as the IRA Se 87.80%,Sp 92.31%.STⅢ↑STⅡ↑ means the LCX as the IRA Se 92.31%,Sp 87.80%.[Conclusion]Electrocardiogram can help to diagnose the IRA in AIMI.
