Key result
Heart rate and heart rate variability in newborns are determined by multiple factors, primarily heritability and maturation, with prematurity demonstrating higher heart rates and reduced variability.
This review highlights the complex, multifactorial determinants of heart rate and heart rate variability in newborns, emphasizing the roles of maturation and specific autoregulatory mechanisms.

HR determinants in newborns merit cautious monitoring use; hypothesis-generating and leaves open prospective validation.
Javorka et al. (2011) conducted a review in Heart rate and heart rate variability in newborns. Determinants of heart rate and heart rate variability was evaluated. Heart rate and heart rate variability in newborns are determined by multiple factors, primarily heritability and maturation, with prematurity demonstrating higher heart rates and reduced variability.
