Abstract

Background: Chronic obstructive pulmonary diseases (COPD), a broad spectrum of respiratory diseases represents a worldwide problem. Electrocardiographic (ECG) findings may help in clinical decision making regarding this disease entity.

Aims: To evaluate the extent and diagnostic values of ECG changes among COPD patients suffering from broad spectrum of respiratory diseases. MATERIAL #ENTITYSTARTX00026;

Methods: A hospital based cross-sectional study was conducted in Sworoop Rani Nehru Hospital, Allahabad in Eastern Uttar Pradesh (UP), India. A sample of 60 patients attending respiratory diseases OPD for treatment of various respiratory problems including 14 COPD patients was selected randomly during 2000-2001. Patients of respiratory diseases were also evaluated electrocardiographically along with other investigations.

Results: Respiratory problems were more common among rural males of low socio-economic group. COPD particularly chronic bronchitis was the commonest respiratory problem next to pulmonary tuberculosis. Inspite of normal heart rate observed in 71.4% COPD patients, ECG changes were present in 35.7% COPD patients. Peaked P-wave was observed in 35.7% COPD patients, whereas duration of QRS complex was abnormal in only 8.1% of the patients. None of the COPD patients showed abnormal P-wave duration. ECG changes were found less sensitive (35.7%) but highly specific (95.6%).

Conclusion: Diagnostic values of ECG among patients with respiratory problems suggest that COPD patients should be screened electrocardiographically in addition to other clinical investigations.

Keywords: Chronic obstructive pulmonary diseases (COPD); Electrocardiographic changes; Sensitivity; Specificity.
