摘要
目的通过对急性下壁心肌梗死时心电图Ⅱ、Ⅲ导联ST段抬高幅度(STⅡ/Ⅲ比值)的比较分析,来预测梗死相关动脉(infarction related artery IRA)。方法回顾性分析72例首次急性下壁心肌梗死患者的入院心电图与冠状动脉造影资料。结果对急性下壁心肌梗死时心电图指标STⅡ/Ⅲ与IRA关系的统计分析表明,STⅡ/Ⅲ在右冠状动脉(RCA)组绝大多数小于1而左旋支(LCX)组多大于等于1(P<0.01),排除RCA和LCX皆有显著病变的病例后仍然P<0.01。结论心电图STⅡ/Ⅲ比值是预测急性下壁心肌梗死患者IRA的较准确的指标。
Objective To investigate value of the electrocardiogram STⅡ/Ⅲ ratio in predicting the infarct-related artery（IRA） in inferior wall acute myocardial infarction. Methods The early electrocardiogram and coronary angiographic findings were retrospectively analyzed in 72 patients with first time inferior wall acute myocardial infarction. Results The STⅡ/Ⅲ ratio was 〈1 in most cases of the RCA group, whereas it was ≥1 in most cases of the LCX group （P〈0.01）.After the patients with distinct lesion in both arteries were excluded, the p value was almost the same （P〈0.01）. Conclusion The STⅡ/Ⅲ ratio is an accurate electrocardiographic criteria for predicting IRA in inferior wall acute myocardial infarction.
