目的探讨心电图在急性ST段抬高型心肌梗死诊治及预后中的价值。方法对患者进行18导联心电图检查、记录,3通道进行同时记录;随后根据患者的标志性心肌损伤物以及冠状造影来进行诊断。结果研究显示,有28例患者表现为缺血性J波,其中有9例(32.14%)缺血性J波患者出现了室性心律失常现象;有52例患者无缺血性J波,其中有10例(19.23%)无缺血性J波患者出现了室性心律失常现象;由此可知,患有缺血性J波的患者其室性心律失常发生率要高于无缺血性J波患者(P<0.05)。此外,在80例患者中预判正确的有60例,占到总数的75.00%;预判错误的有15例,占到总数的18.75%;无法判断的有5例,占到总数的6.25%。结论心电图获取的操作方式简单,对病情的反映时间较快;更为重要的是它能够帮助医师判断患者的心肌梗死部位与范围,为医师进行针对性的后续提供参考,并提高患者的预后。
Objective To investigate the value of electrocardiogram in diagnosis and prognosis of acute ST-segment elevation myocardial infarction. Methods 18-lead electrocardiogram (ECG) examination, recording and 3-channel electrocardiography were performed on the patients, and then the patients were diagnosed by the landmark myocardial injury and coronary angiography. RESULTS: Twenty-eight patients showed ischemic J waves, including ventricular arrhythmias in 9 (32.14%) ischemic J waves; 52 patients had no ischemic J waves Ventricular arrhythmia occurred in 10 patients (19.23%) without ischemic J wave; therefore, the incidence of ventricular arrhythmia in patients with ischemic J waves was higher than that in patients without ischemic J Wave patients (P <0.05). In addition, among the 80 patients, 60 cases were correctly predicted, accounting for 75.00% of the total; 15 cases were false-positive, accounting for 18.75% of the total; 5 cases were unidentifiable, accounting for 6.25% of the total. . Conclusions ECG acquisition is easy to operate and has a quick response time to disease. More importantly, it can help physicians to determine the location and scope of myocardial infarction in patients and provide reference for follow-up and improve patient prognosis.
