摘要
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 identify the clinical value of monitoring the dynamic electrocardiogram changes of poor R wave progression in precordial leads in the diagnosis of myocardial infarction in patients with poor R wave progression in preeordial leads. Methods 25 case with poor R wave progression in precordial leads were classified into group A （12case） patients with myocardial infarction and group B （13cases） without myocardial infarction. Dynamic electrocardiogram changes in 24 hours were monitored in all 25 patients, combined with medical history, other examination and clinical data were retrospectively analyzed. Results 7 cases in group A （58.33%） and 1 case in group B（7.69%） were found dynamic electrocardiogram changes in 24 hours. There was a significant difference in the dynamic electrocardiogram changes incidence rate of the two groups in the 24 hours （p 〈0.01）. Conclusions Monitoring the dynamic electrocardiogram changes of poor R wave progression in precordial leads would help to clear myocardial infarction, patients with poor R wave progression in precordial leads should be diagnosised by monitoring the dynamic electrocardiogram changes and combined with clinical signs and other methods,thus to avoid misdiagnosis.
