Supports statistical testing of neonatal heart rate complexity; leaves open clinical validation before adoption in monitoring.
Joshua Richman (2007) studied Heart rate dynamics of premature infants. Sample Entropy (SampEn) statistics was evaluated on Statistical properties and variance of SampEn. Sample Entropy statistics are asymptotically Gaussian under general conditions, enabling point estimates of variance and statistical tests to quantify order in neonatal heart rate dynamics.
