Forty patients with chronic obstructive lung disease (chronic bronchitis, emphysema, and chronic bronchitis and emphysema) in the quiescent state were included in a study relating pulmonary function to various electrocardiographic changes. Correlation between P wave amplitude and FEV1/VC was found to be good. A fair correlation was found between R amplitude in lead 1 vs FEV1/VC, P axis vs FEV1/VC, and P axis vs RV/TLC. A poor correlation was found between P amplitude vs RV/TLC, ÂQRS vs FEV1/VC, ÂQRS vs RV/TLC and R amplitude in lead 1 vs RV/TLC. Scatter diagrams with their linear regression equations are presented for these reiationships. The findings indicate that the electrocardiogram may serve as a means for estimating the degree of pulmonary impairment.
