Correlation of Q T and P Wave Dispersion to Ventilatory Functions in COPD Patients
Journal Title: PARIPEX-Indian Journal of Research - Year 2016, Vol 5, Issue 5
Abstract
Introduction: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death, affects more than 2.7 million people in India. Patients with COPD also carry an increased risk of mortality due to tachyarrhythmia and sudden cardiac death due to prolonged QT and P wave dispersion. Method: 50 diagnosed COPD patients of chronic bronchitis and emphysema was compared with 50 healthy control. ECG was recorded using Clarity Med ECG 50-1 CH. and pulmonary function tests were performed with 702 Helios Spirometer (RMS, India). ECG parameters and pulmonary function tests were compared by using unpaired ‘t’ test. Correlation was done by Pearson’s co-relation coefficient and p value was calculated. Observations and Results: QT & P wave dispersion is found to be prolonged in COPD patients compared to healthy control group and there was negative correlation of QT and P wave dispersion with various spirometric parameters. Conclusion: Prolonged QT dispersion in COPD patients is associated with generation of life threatening rhythm disturbances and sudden cardiac death. There is Intriguing relationship between the QT dispersion and functional respiratory parameters.
