Key result
Baroreflex sensitivity increased progressively with postnatal age, averaging 6.4, 10.5, and 16.0 ms/mmHg at 2-4 weeks, 2-3 months, and 5-6 months, respectively (P<0.05).
Observational (n=30)
p-value: p=< 0.05
Baroreflex sensitivity increases progressively during the first 6 months of life in term infants, and accounting for heart period delay improves time-domain estimates.

May facilitate BRS assessment in infants; leaves open validation before clinical adoption.
Yiallourou et al. (2010) conducted an observational in term infants (n=30). Postnatal age was evaluated on Baroreflex sensitivity (BRS) (p=< 0.05). Baroreflex sensitivity increased progressively with postnatal age, averaging 6.4, 10.5, and 16.0 ms/mmHg at 2-4 weeks, 2-3 months, and 5-6 months, respectively (P<0.05).
