Key result
Idiopathic respiratory distress syndrome was associated with reduced long-term heart rate variability in newborn infants, and persistent reduction was associated with increased mortality.

Reduced long-term heart rate variability in sick newborns with respiratory distress syndrome is associated with disease severity and increased mortality.
Jenkins, J. G., Reid, M. McC. and McClure, B. G. (Special Care Baby Unit, Royal Maternity Hospital, and Department of Child Health, Queen's University, Belfast, N. Ireland). Study of heart rate variability in sick newborn infants. Acta Paediatr Scand, 69: 393, 1980.—Heart rate variability has been studied in a group of 66 newborn infants for periods of up to 72 hours from birth. Long term variability was reduced in infants suffering from the idiopathic respiratory distress syndrome and this was more marked with severe respiratory distress requiring mechanical ventilation. Persistent reduction in long term variability was associated with increased mortality. Reduction in heart rate variability may be due to high levels of sympathetic activity.

Jenkins et al. (1980) conducted an observational in Sick newborn infants (n=66). Idiopathic respiratory distress syndrome was evaluated on Long term heart rate variability and mortality. Idiopathic respiratory distress syndrome was associated with reduced long-term heart rate variability in newborn infants, and persistent reduction was associated with increased mortality.
