Obstructive sleep apnea syndrome and autonomic dysfunction
Autonomic nervous system (ANS) has been extensively explored in obstructive sleep apnea (OSA).Autonomic alterations in these patients have been described by means of several methods, evaluating ANS function both directly with microneurography and indirectly through baroreflex sensitivity (BRS, by the sequence method or the cross-spectral approach), heart rate variability analysis (HRV, both in the time and frequency domain) during sleep and wake, or conventional laboratory tests, including cold pressor test, hand grip test or measurement of urinary cathecolamine excretion.
