不典型急性心肌梗死患者的心电图变化研究

Study on the Changes of Electrocardiogram in Patients with Atypical Acute Myocardial Infarction

目的研究不典型急性心肌梗死患者心电图的变化情况。方法选取我院2014年8月至2016年8月收治的100例不典型急性心肌梗死患者,所有患者均行心电图检查,观察心电图变化情况。结果 100例患者中,48例(48.0%)患者出现心电图改变,其中T波高尖发生率最高(P<0.05)。前降支、回旋支以及右冠状动脉罪犯血管患者心电图检出率均高于无病变患者(P<0.05)。CP时间为2~4 h的患者心电图检出率最高(P<0.05)。结论不典型急性心肌梗死患者心电图检查中,T波高尖较为多见,心电图变化多发生于胸痛发作后2~4 h,掌握不典型急性心肌梗死的心电图变化情况对早期诊断具有重要意义。

Objective To study the changes of electrocardiogram in patients with atypical acute myocardial infarction. Methods 100 cases of patients with atypical acute myocardial infarction admitted to our hospital from August 2014 to August 2016 were selected and given electrocardiogram examination. The changes of electrocardiogram were observed. Results Among 100 cases of patients, 48 cases （48.0%） of patients had electrocardiogram changes, and the incidence of T-wave height was highest （P 〈0.05）. The electrocardiogram detection rates of patients with anterior descending branch, circumflex branch and right coronary artery were higher than those of patients without lesion （P 〈0.05）. The electrocardiogram detection rate of patients with CP time within 2 to 4 hours was highest （P 〈0.05）. Conclusions T-wave height is more common in the electrocardiogram examination of patients with atypical acute myocardial infarction. Electrocardiogram changes occur in 2 to 4 hours after chest pain. Mastery of electrocardiogram changes of atypical acute myocardial infarction is of great significance for early diagnosis.
