Association between spectral analysis of heart rate variability and pulmonary function tests in bronchial asthma patients

The parasympathetic vagus nerve supplies the heart and lung. Parasympathetic activity modifies rate force of contraction in Airway bronchial smooth muscle constriction hypersecretion mucus lungs. There is a link between these two components. Hence this study designed to find association Spectral analysis variability pulmonary function tests asthma patients. In study, 30 asthmatic patients were recruited from respiratory medicine outpatient department healthy volunteers included. Pulmonary was recorded physiology department. parameters found significantly reduced patient it shows obstructive lung diseases. Heart statistically decreased mean HR, VLF ms2, LF ms2 when compared controls. HF increased patient. These represent hyperactivity. This concluded there dominance might be one reasons for increases airway bronchoconstriction mucus. negative correlation FEV1 value ms2. A decrease leads an increase
