Abstract

This research examined autonomic dysfunction in heart rate variability and spectral disturbances in COPD patients. The research included 100 COPD patients and 100 healthy as control. The research covered Mild & Moderate COPD patients. Excludes severe and very severe COPD patients also avoided sand miners and passive smokers. Study used case-control design. The result revealed that COPD sufferers had a lower FEV1% (1.90.39) than controls. COPD patients had a lower FVC% (56.428.41) than controls. COPD sufferers had a 2.750.62 higher RV (L) than controls. COPD sufferers had a 2.750.62 higher TLC (L) than controls. Cases and controls HRV and frequency parameters (LF/HF) ratio shows a considerable difference, although LF nu and HF nu indicate no difference. A high ratio of low to high frequency activity indicates parasympathetic activation. Comparing Time Domain Parameters, HRV of Cases and Controls, the mean RR interval of the control group appears to rise, giving the appearance that the smaller mean RR interval in cases reflects a fast heart rate due to a shift toward sympathetic activity. COPD patients have lower HRV, which indicates ANS dysfunction with sympathetic hyperactivity. Regulated breathing increases parasympathetic activity and HRV, although not much. So the study will try to show that weather controlled breathing slow and deep will affect the ANS controlling of the heart variables are not
