摘要
目的探讨慢性阻塞性肺疾病患者P波电轴垂直化及其与肺功能的相关性。方法选择2016年1月—2017年6月就诊的慢阻肺患者76例为观察组,健康体检者80例为对照组,两组均完成心电图和肺功能检查,比较两组的P波电轴,并分析其与第1 s用力呼气容积占用力肺活量比值(FEV1/FVC)的相关性。结果观察组P波电轴垂直化较对照组显著,差异有统计学意义(P<0.05),Pearson相关系数分析显示P波电轴与FEV1/FVC呈显著负相关(P<0.05)。结论 P波电轴与肺功能呈显著负相关性,可作为慢性阻塞性肺疾病的重要筛查指标。
Objective To explore the vertical P-wave axis in patients with chronic obstructive pulmonary disease(COPD)and its correlation with pulmonary function.Methods 76 patients diagnosed with COPD from January,2016 to June,2017 were selected as the observation group,and another 80 healthy volunteers were chosen as the control group.Both the two groups received electrocardiograms and pulmonary function tests.The P-wave axis between the two groups were compared,and its correlation with FEV1/FVC were analyzed.Results The P-wave axis of the observation group was significantly higher than that in the control group(P<0.05).Pearson correlation coefficient analysis showed that P-wave axis was negatively correlated with FEV1/FVC(P<0.05).Conclusion P-wave axis shows significant negative correlation with pulmonary function,which is an important screening test for COPD.
