目的探讨急性心肌梗死患者在发病后的超急性期心电图非典型改变的临床特点。方法 200例心肌梗死患者,根据就诊时间以2 h为一个时间段将患者分为组1(0 h6 h,61例)。分别检测四组患者的心电图,并比较分析各组的心电图特点。结果 200例患者中,心电图结果呈阳性51例,阳性率为25.50%,其中6例Q波改变,占3.00%;10例R波改变,占5.00%;19例T波改变,占9.50%;16例ST段改变,占8.00%。组2患者较组3和组4患者更容易出现超急性期心电图非典型改变(P<0.05)。结论急性心肌梗死患者的心电图在超急性期会出现明显的非典型改变,多发生在2~4 h,以T波为主。了解急性心肌梗死患者的超急性心电图非典型改变的临床特点,能为诊断急性心肌梗死提供可靠有效的依据。
Objective To investigate the clinical characteristics of atypical changes of hyperacute ECG after acute myocardial infarction in patients with acute myocardial infarction. Methods A total of 200 patients with myocardial infarction were divided into group 1 (0 h 6 h, 61 patients). The electrocardiogram (ECG) of the four groups of patients were detected, and the ECG characteristics of each group were compared. Results Of the 200 patients, the positive rate of electrocardiogram was 25.50%. Among them, the Q wave changed in 6 cases (3.00%), the change of R wave in 10 cases (5.00%), the change of T wave in 19 cases (9.50%), 16 cases of ST segment changes, accounting for 8.00%. Patients in group 2 were more likely to have atypical changes in hyperacute electrocardiogram than those in patients in groups 3 and 4 (P <0.05). Conclusion ECG in patients with acute myocardial infarction in the hyperacute stage will appear obvious atypical changes, mostly occurred in 2 ~ 4 h, mainly T wave. To understand the clinical features of atypical changes of hyperacute ECG in patients with acute myocardial infarction can provide a reliable and effective basis for the diagnosis of acute myocardial infarction.
