Key result
Age, respiration, and behavior associate with long-term HRV in preterm infants, unlike BP and pO2.
Observational (n=4)
In healthy preterm infants, long-term heart rate variability is significantly influenced by age, respiration rate, and behavior, which must be accounted for before using it as a monitoring tool.

HRV assessment in preterm infants must account for age, respiration, and behavior; case report leaves open its role as a monitoring tool.
Ravenswaaij‐Arts et al. (1990) conducted an observational in Healthy preterm newborns (n=4). Physiological parameters (age, respiration rate, behaviour, blood pressure, transcutaneous pO2) was evaluated on Long term heart rate variability. Physiological parameters including age, respiration rate, and behavior influenced long-term heart rate variability in healthy preterm infants, whereas blood pressure and transcutaneous pO2 did not.
