慢性阻塞性肺病(简称慢阻肺)之心电图改变与肺功能损害有一定关系,已为临床重视。本文报道316例慢阻肺患者的心电图(P波振幅,P及QRS电轴)与肺功能中的一秒率(FEV_1/FVC％)及最大呼气中期流速(MMEF)作为气道阻塞指标之间的关系,进行回归分析,结果见表1、2。由于慢支炎,阻塞性肺气肿及肺心病患者均有不同程度的肺功能减退。从表1可见能反映肺心病特征的异常心电图之出现率随气道阻塞的严重程度而增高(P<0.001)。其中P波振幅、P及QRS电轴分别与一秒率和MM EF均有极明显的负相关(P<0.001),此与
Chronic obstructive pulmonary disease (referred to as chronic obstructive pulmonary) ECG changes and lung function damage has a certain relationship, has been clinically important. This paper reports the electrocardiogram (P wave amplitude, P and QRS axes) and pulmonary function in one second (FEV_1 / FVC%) and maximal expiratory flow rate (MMEF) in 316 patients with COPD as indicators of airway obstruction The relationship between regression analysis, the results shown in Table 1,2. Due to chronic myelitis, obstructive pulmonary emphysema and pulmonary heart disease patients have varying degrees of lung dysfunction. As can be seen from Table 1, the incidence of abnormal ECG that can reflect the characteristics of pulmonary heart disease increased with the severity of airway obstruction (P <0.001). P wave amplitude, P and QRS axis were significantly negatively correlated with the one-second rate and MM EF (P <0.001)
