Heart rate response related to body movements in healthy and neurologically damaged infants during sleep.
Sixteen infants were studied with the static charge sensitive bed (SCSB) method. This method is newly developed for neonatal recordings and it allows recording of body movements, respiration and of the ballistocardiographic signal. Eight healthy newborn infants and eight infants with clear neurological dysfunction were recorded and the heart rate acceleration-deceleration responses to body movements during sleep were studied. Healthy infants had a constant heart rate response to body movements but infants with neurological symptoms had either too weak or hyperactive reactions. This finding can be explained by abnormal function of the autonomic nervous system in infants with disturbance of the central nervous system.
