摘要
【摘 要】目的：探讨心电图在急性心肌梗死超急性期诊断中的价值。方法：选取 80例 2018年 3月 -2019年 3月本院收治的急性心肌梗死超急性期患者为研究对象，按发病时间分为三组， A组 40例发病 <2h， B组 30例发病 2～ 6h， C组 10例发病 6～ 8h。均随时对患者进行心电图监测，并且将心电图的 Q波和 ST段，以及其 T波进行记录，对阳性改变率做出有效分析。结果是在急性心肌梗死超急性期中，利用 ST段和 T波变化，能够进行敏感性以及特异性的有效预测，预测值和阴性预测值都比 Q波高。在 A组中，患者的阳性改变率显著比 B组 C组高。在 A组中，心梗患者的 ST段抬高型改变发生率显著比非 ST段抬高型的心梗患者要高（ P<0.05）。针对急性心肌梗死超急性期的患者，使用随时的心电图监测，可以对患者病情进行诊断和预测，为患者的诊断与治疗提供了巨帮助，值得推广。

[Abstract] Objective: To explore the value of electrocardiogram in the diagnosis of hyperacute stage of acute myocardial infarction. Methods: 80 patients with super acute myocardial infarction admitted to our hospital from March 2018 to March 2019 were selected as the research objects. According to the time of onset, they were divided into three groups: 40 patients in group A were less than 2h, 30 patients in group B were 2-6h, and 10 patients in group C were 6-8h. All patients were monitored at any time, and the Q wave, ST segment and T wave of ECG were recorded, and the positive change rate was effectively analyzed. The results showed that the sensitivity and specificity of ST segment and T wave could be effectively predicted in hyperacute stage of AMI. The predictive value and negative predictive value were higher than Q wave. In group A, the positive rate was significantly higher than that in group B and group C. In group A, the incidence of ST elevation was significantly higher than that of non ST elevation (P < 0.05). For the patients with acute myocardial infarction in hyperacute stage, using ECG monitoring at any time can diagnose and predict the patient's condition, which provides great help for the diagnosis and treatment of patients and is worth promoting.
