摘　　要：目的探讨老年慢性阻塞性肺疾病(COPD)的临床特征及心电图I导联QRS振幅在老年COPD患者诊断中的价值。方法选取彭州市人民医院收治的老年COPD患者52例(COPD组),同期非COPD患者130例(非COPD组)。比较两组临床特征并分析心电图在老年COPD患者诊断中的价值。结果COPD组吸烟、支气管哮喘占比高于非COPD组。两组P波电轴、P波时间、QRS波电轴、I导联QRS波的振幅比较,差异均有统计学意义(P<0.05)。COPD组I导联QRS波的振幅与FEV1/FVC呈正相关(P<0.001)。I导联QRS波的振幅预测COPD的最佳截点为0.57 mv,预测COPD患病的敏感度为67.9%,特异度为71.2%。结论I导联QRS波的振幅0.57 mv是预测COPD的重要诊断标准,有望成为COPD新的预测指标。Objective To explore the clinical characteristics of elderly patients with chronic obstructive pulmonary disease(COPD),and to explore the significance of QRS amplitude in ECG lead I in the diagnosis of elderly patients with COPD.Methods Fifty-two COPD elderlypatients admitted to our hospital were selected,and 130 non-COPD patients during the same period were randomly selected.The clinical characteristics were compared between the two groups and the significance of ECG in the diagnosis of COPD in the elderly was analyzed.Results Compared with non-COPD patients,COPD patients had more incidences of smoking and bronchial asthma.There were significant differences in ECG characteristics such as P wave axis,P wave time,QRS wave axis and amplitude of QRS wave in lead I between the two groups(P<0.05).In the COPD group,the amplitude of QRS wave in lead I was positively correlated with FEV1/FVC(P<0.001).The best intercept point of amplitude of the QRS wave in lead I predicting COPD was 0.57mv.The sensitivity and specificity of the prediction were 67.9%and 71.2%,respectively.Conclusion Anamplitude of 0.57mv of the QRS wave of lead I is an important diagnostic criterion for predicting COPD.It is expected to become a new predictive index for the diagnosis of COPD.
