摘要
目的探讨急性下壁心肌梗死(AIMI)时心电图对分析心肌梗死相关动脉和闭塞位置的作用。方法纳入在我院治疗并行冠脉造影的AIMI患者90例,分为A组(右冠状动脉近段梗死)、B组(右冠状动脉远段梗死)、C组(左回旋支梗死),各30例。分析心电图对判断心肌梗死相关动脉和闭塞位置的作用。结果 A、B、C三组导联STV_3↓值依次升高,STⅢ↑值依次降低,差异显著(P<0.05);A组患者STV3/STⅢ<0.5占比最大,为70.00%;B组0.5≤STV3/STⅢ≤1.2占比最大,为63.33%;C组STV3/STⅢ>1.2占比最大,为63.33%,组间比较,差异显著(P<0.05)。STV_3/STⅢ<0.5、0.5≤STV3/STⅢ≤1.2及STV3/STⅢ>1.2时,组间比较,A、B、C组的灵敏度、特异度、阳性、阴性预测值分别最高(P<0.05)。结论心电图STV3/STⅢ是判断心肌梗死相关动脉和闭塞位置的有效指标。
Objective To discuss the effect of ECG on analysis of related artery and blocking position in acute inferior myocardial infarction（AIMI）. Methods Ninety cases of patients with AIMI who underwent coronary angiography in our hospital were enrolled in this study, and were divided into group A（proximal segment of right coronary infarction）, group B（distal segment of right coronary infarction） and group C（left circumflex artery infarction）, with 30 cases in each group. The effect of ECG on analysis of related artery and blocking position of AIMI was analyzed. Results STV3↓ in groups A, B and C increased in turn, STⅢ↑ decreased in turn（P〈0.05）. STV_3/STⅢ0.5 accounted for the largest proportion in group A,which was 70.00%; 0.5≤STV3/STⅢ≤1.2 accounted for the largest proportion in group B, which was 63.33%; STV3/STⅢ〉1.2 accounted for the largest proportion in group C, which was 63.33%, the differences were significant（P〈0.05）. In STV3/STⅢ〈0.5, 0.5≤STV3/STⅢ≤1.2 and STV3/STⅢ〉1.2, the sensitivity, specificity, positive and negative predictive values were the highest in groups A, B and C respectively（P〈0.05）. Conclusion ECG STV3/STⅢ is the effective indicator to determine related artery and blocking position of AIMI.
