NCT00766584

Brief Summary

The regulatory effects of the autonomic nervous system (ANS) concern almost all organs which permanently feed information back to this global biological vigilance system controlling allostasis. Heart rate fluctuations are highly dependent on ANS control, making the heart one of the best indicators of ANS activity. Low ANS activity level is associated with severe cardiac and cerebral events, as well as to death from any cause in the general population. It is even associated with sleep apnea/hypopnea.
