【摘要】：目的:對(duì)急性下壁心肌梗死患者的心電圖資料進(jìn)行回顧性研究，分析和比較心電圖改變與冠狀動(dòng)脈造影及臨床特點(diǎn)的對(duì)應(yīng)性關(guān)系。探討急性下壁心肌梗死患者的體表心電圖對(duì)梗死相關(guān)血管及閉塞部位的預(yù)測(cè)價(jià)值。方法:選取86例急性下壁心肌梗死患者，根據(jù)冠狀動(dòng)脈造影結(jié)果分為右冠狀動(dòng)脈(RCA)病變組和左冠狀動(dòng)脈(LCA)病變組。對(duì)比分析其心電圖改變與冠狀動(dòng)脈造影結(jié)果及臨床特點(diǎn)。結(jié)果:（1）本文研究提示造影顯示正常冠狀動(dòng)脈者均不合并糖尿病，急性下壁心肌梗死合并糖尿病患者中雙支、多支血管病變居多；年齡越大，，累及病變血管支數(shù)越多。（2）急性下壁心肌梗死患者IRA為L(zhǎng)CX者均為男性患者；后壁、右室心肌梗死常與下壁心肌梗死并存；并發(fā)右室梗死者，其IRA均為RCA，且病變節(jié)段均位于右冠狀動(dòng)脈近段；冠狀動(dòng)脈造影正常者均為單純急性下壁心肌梗死，并未合并其它部位心肌梗死。（3）通過(guò)ST↓aVL＞ST↓I指標(biāo)判斷IRA為RCA病變檢出率高。（4）不同導(dǎo)聯(lián)ST偏移標(biāo)準(zhǔn)判斷IRA為RCA或LCX的靈敏度、特異度均不高。（5）對(duì)所有下壁心肌梗死患者，均應(yīng)該及時(shí)準(zhǔn)確地記錄右胸導(dǎo)聯(lián)心電圖。結(jié)論:心電圖對(duì)診斷下壁急性心肌梗死相關(guān)血管及其臨床特點(diǎn)具有重要的預(yù)測(cè)價(jià)值。
[Abstract]:Objective: to study the electrocardiogram data of patients with acute inferior wall myocardial infarction (AMI). To analyze and compare the corresponding relationship between electrocardiogram changes and coronary angiography and clinical features. To explore the predictive value of surface electrocardiogram in patients with acute inferior wall myocardial infarction on infarct-related vessels and occlusion sites. 86 patients with acute inferior wall myocardial infarction, According to the results of coronary angiography, the patients were divided into two groups: right coronary artery lesion group (RCA) and left coronary artery lesion group (LCA). The electrocardiogram changes, coronary angiography results and clinical characteristics were compared and analyzed. Patients with normal coronary artery were not complicated with diabetes, In the patients with acute inferior wall myocardial infarction complicated with diabetes mellitus, the patients with IRA were male, the patients with IRA were male, the patients with IRA were male, the patients with acute inferior wall myocardial infarction complicated with diabetes mellitus, the patients with multiple vessel disease were mostly; the older the age, the more the number of branches involved in the lesion. Right ventricular myocardial infarction often coexisted with inferior myocardial infarction. The IRA of patients complicated with right ventricular infarction were all located in the proximal segment of right coronary artery, and those with normal coronary angiography were all simple acute inferior myocardial infarction. No other myocardial infarction. 鈫揂VL > St. 鈫揟he sensitivity and specificity of different lead St deviation criteria in judging whether IRA was RCA or LCX was not high. 5) in all patients with inferior myocardial infarction, the detection rate of IRA was high. Conclusion: electrocardiogram (ECG) has important predictive value in the diagnosis of inferior wall acute myocardial infarction (AMI) related blood vessels and its clinical characteristics.
