目的对急性心肌梗死(AMI)患者的心电图进行了统计分析,以了解AMI患者的心电图特点。方法收集临床诊断AMI患者108例的心电图及相关的症状、体征及心律失常等资料。结果 50~59岁男性患者AMI发病率最高,下壁心肌梗死,广泛前壁心肌梗死发病率较高,入院后观察到典型的ST段抬高和Q波出现的AMI患者在临床上不足60%。结论部分AMI患者ECG没有典型表现,要注意对ST段、T波及异常Q波特点的观察,特别是注意其动态变化,避免误诊误治。
Objective To analyze the electrocardiogram of patients with acute myocardial infarction (AMI) so as to understand the characteristics of electrocardiogram in patients with AMI. Methods The electrocardiogram and related symptoms, signs and arrhythmia of 108 patients with AMI were collected. Results The incidence of AMI was the highest in men aged 50-59 years. The incidence of myocardial infarction in inferior wall and extensive anterior myocardial infarction were higher than those in typical AMI patients with ST-segment elevation and Q wave after admission. The incidence of AMI was less than 60% . Conclusion Some patients with AMI have no typical ECG. We should pay attention to the observation of ST segment, T wave and abnormal Q wave characteristics, especially pay attention to its dynamic changes and avoid misdiagnosis and mistreatment.
