Key result
Spectral-temporal heart rate analysis of 24-hour recordings in newborns revealed diverse spectral patterns, indicating no single short segment can unambiguously characterize physiological state.
Population

Short HRV segments may misrepresent newborn autonomic state; leaves open validation of extended recordings for research standardization.
Observational
Spectral-temporal analysis of 24-hour heart rate variability in newborns reveals dynamic changes in autonomic regulation that cannot be captured by short-segment recordings.
Нароган et al. (2007) conducted an observational in Newborns. Spectral and spectral-temporal heart rate analysis was evaluated on Spectral behavior of cardiointervals. Spectral-temporal heart rate analysis of 24-hour recordings in newborns revealed diverse spectral patterns, indicating no single short segment can unambiguously characterize physiological state.
