Abstract              Background: COPD is a leading cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing. The prevalence and burden of COPD are projected to increase in the coming decades due to continued exposure to COPD risk factors and the changing age structure of the world population.¹ Materials and Methods: In the present study 50 cases were selected on the basis of simple random sampling method from the Medical Wards/OPD, B.K.L. Walavalkar Rural Medical College from January 2018 to December 2019. Results: 50 patients of chronic obstructive pulmonary disease were studied Majority of patient had moderate airflow obstruction. The commonest ECG changes were P wave axis ≥+90⁰, QRS axis ≥ + 90and P wave height in L2 ≥ 2.5mm. R wave in V₆ < 5 mm and R/S ratio in V₅ V₆ ≤1 were seen less commonly. Unifocal right ventricular ectopics and RBBB were seen rarely. Conclusion: E.C.G. changes correlate significantly with low value of FEV1/FVC ratio. The commonest ECG changes were P wave axis ≥+90⁰, QRS axis ≥ + 90 and P wave height in L2 ≥2.5mm. R wave in V₆ <5 mm and R/S ratio in V₅ V₆ ≤1 were seen less commonly. Unifocal right ventricular ectopics and RBBB were seen rarely.
