Abstract
To help understand the control of cardiovascular function of young infants during sleep, the frequency spectrum of the heart rate was obtained during quiet and active sleep in six infants. It was found that power in the low-frequency band (0.04-0.15 Hz) was significantly higher during active sleep (p < 0.02). Power in the high-frequency band (0.15-0.8 Hz) did not change significantly. The L/H ratio was also significantly higher during active sleep. This is consistent with increased cardiovascular sympathetic influences in active sleep compared to quiet sleep.
