Restless leg syndrome and slow coronary flow. Is it inflammation or autonomic nervous system?

handgrip. There are other approaches for evaluating the autonomic nervous system by heart rate variability (HRV) parameters from shortor longterm monitoring (2). We agree that HRV and bedside autonomic function tests for evaluating the autonomic nervous system provide complementary information regarding autonomic regulatory mechanisms in health and disease. However, the bedside autonomic function tests were more feasible for us during the study. We also considered that spectrum bias may account for differences in the reported results between the investigations. Therefore, in order to point out the difference between the cardiovascular autonomic function of RA patients and general population, we will design another prospective cohort study with complementary and more sensitive tests.
