Electrocardiographic changes in COPD

Introduction: Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous clinical syndrome found in 6?8% of the entire population. In human being, the respiratory and circulatory systems are so intimately related that changes in one, sooner or later may cause changes in the other. In COPD patients, functional and structural changes of the respiratory system deeply influence cardiovascular function. Methodology: Cross-sectional study was conducted in patients of chronic obstructive pulmonary disease admitted in medical ward & emergency ward. Out of 100 cases, 30 were females and 70 were males. Most of the patients were diagnosed clinically and after radiological investigation & ECG. Discussion: Maximum number of patients belonged to 51-60 years. 65% cases showed right axis deviation. 35% showed p pulmonale, 70% showed right axis deviation. In 65% cases position of heart was vertical. In 22% cases low voltage QRS complex was seen. 62% cases dominant S wave in lead V5-V6. Conclusion: Most common findings in ECG of patients with chronic obstructive pulmonary disease were indicating right axis deviation, clockwise rotation of heart, vertical position of heart.
