慢性阻塞性肺疾病患者肺功能损害程度与心电图异常的相关性OA

Objective To investigate the correlation between the severity of pulmonary dysfunction and electrocardiographic abnormalities in patients with chronic obstructive pulmonary disease(COPD),so as to provide reference for clinical disease evaluation,and the prevention and treatment of complications.Methods A retrospective analysis was conducted on data from 900 patients who had undergone routine electrocardiogram(ECG)and pulmonary function testing.Among these,395 patients with abnormal pulmonary function were screened,including 198 patients with COPD.These 395 patients were divided into four groups according to age,and the detection rate of COPD in each group was calculated.According to the pulmonary function grading criteria in the"Guidelines for the diagnosis and treatment of chronic obstructive pulmonary disease(2021 revised edition)",198 COPD patients were further classified into four groups based on the severity of pulmonary dysfunction:mild(72 cases),moderate-moderately severe(52 cases),severe(32 cases),and extremely severe(42 cases)groups.ECG findings were compared among the groups to analyze the incidence of complicated ST-T abnormalities,premature beats,tachycardia,atrial abnormalities,ventricular high voltage or hypertrophy,bundle branch block,and abnormal QRS axis.Results The detection rate of COPD was higher in males than that in females[139 cases(60.7％)vs.59 cases(35.5％)].The detection rate of COPD was the highest in the＞80 years group across age groups.The proportion of patients with concomitant electrocardiographic abnormalities increased with the deterioration of pulmonary function impairment.Conclusion The incidence of electrocardiographic abnormalities in patients with COPD is closely related to disease severity.With the increase of age and progression of the disease,the incidence of concomitant ECG abnormalities rises.Routine ECG examination can serve as an adjunctive tool for disease assessment and prognostic evaluation in COPD patients.
