Diagnostic Values of Electrocardiogram in Chronic Obstructive Pulmonary Disease (COPD).

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.

Reactivation of a tuberculous lesion following bronchography.

A bronchogram was performed on a symptomless patient who had a pulmonary cavity from previously treated tuberculosis. Four days later there was clinical and radiographic evidence of reactivation of the disease and tubercle bacilli were found in the sputum.
