Patients with both HF and COPD usually have significant decreases in their ability to do daily tasks and their overall quality of life. This is because both conditions involve several organ systems and cause disruptions in autonomic regulation and the operation of various organs and bodily processes, including cardiovascular control at rest and during exercise. Heart rate variability (HRV) analysis is a good way to learn more about the cardiovascular system and the mechanisms that control autonomic adjustments. It is also a reliable way to estimate the likelihood of death or a bad prognosis.
