目的明确胸导联R波递增不良心电图患者动态心电图观察在诊断心肌梗死过程中的临床价值。方法 25例心电图表现为胸导联R波递增不良患者分为A组心肌梗死组(12例)和B组非心肌梗死组(13例),所有患者通过24小时内动态心电图观察,结合病史、其他检查检验及住院资料进行临床回顾性分析。结果心肌梗死组12(A组)例患者中有7例(58.33%),13例非心肌梗死组(B组)中1例24小时内有心电图动态变化(7.69%)。两组患者在24小时内心电图动态变化发生率上存在统计学差异(p<0.01)。结论胸导联R波递增不良心电图患者进行动态心电图观察有助明确心肌梗死的诊断,在临床上发现胸导联R波递增不良心电图患者应注意动态观察,并结合病史体征和其他方法加以确诊,避免漏诊。
Objective To determine the clinical value of dynamic electrocardiogram (ECG) in the diagnosis of myocardial infarction in patients with progressive chest radiographs. Methods Twenty-five patients with progressive adverse ECG R wave were divided into group A (n = 12) and group B (n = 13). All patients were observed by dynamic electrocardiogram within 24 hours, Other inspection and hospitalization data for clinical retrospective analysis. Results There were 7 cases (58.33%) of the 12 patients in the AMI group and 1 patient (7.69%) in one of 13 non-MI group (B) within 24 hours. There was a significant difference between the two groups in the incidence of electrocardiographic changes within 24 hours (p <0.01). Conclusions The dynamic electrocardiogram (ECG) observation in patients with progressive chest radiography and R wave increase unhealthy electrocardiogram can help confirm the diagnosis of myocardial infarction. Clinicians should pay attention to the dynamic observation of R wave increasing adverse electrocardiogram and combine with the history and signs and other methods to diagnose the myocardial infarction. Avoid missed diagnosis.
