Abstract :
The aim of our study was to assess differences in autonomic nervous system control during the various sleep states according to age, and to evaluate the influence of some "risk" factors upon this control. Criteria considered were RR intervals and their variability in different frequency bands: a) High frequency (HF)=3 to 8 heartbeat period (HBP); b) Mid Frequency (MF) = 10 to 25 HBP and c) Low Frequency (LF)=30 to 100 HBP. LF variability is mainly under sympathetic control, while vagal reflex mechanisms are involved in HF control (1).
