Research Abstract	We studied the heart rate variability from 20:00 to 8:00 for three days in eighteen severely retarded children (9 boys and 9 girls: mean age 12.1±4.6 years old) to assess the autonomic nerve activity during sleep. LF/HF ratio was significantly higher in the children who required an oral, nasal or trachea suction. This result suggests the possibility that stress of suction causes sympathetic hyperactivity and affects the cardiac autonomic nervous activity during sleep in severely retarded children.
