Abnormal heart rate characteristics of reduced variability and transient decelerations are present early in the course of neonatal sepsis. To investigate the dynamics, we calculated sample entropy, a similar but less biased measure than the popular approximate entropy. Both calculate the probability that epochs of window length m that are similar within a tolerance r remain similar at the next point. We studied 89 consecutive admissions to a tertiary care neonatal intensive care unit, among…

Cardiovascular oscillations at the bedside: early diagnosis of neonatal sepsis using heart rate characteristics monitoring.
TLDR
It is found that measurements of standard deviation, sample asymmetry and sample entropy are highly related to imminent clinical illness.
Uncorrelated Randomness of the Heart Rate Is Associated with Sepsis in Sick Premature Infants
TLDR
Late-onset sepsis is associated with uncorrelated randomness of the HR, and abnormal HR behavior may help to monitor premature infants presenting with frequent and severe bradycardias.
Increased Nonstationarity of Neonatal Heart Rate Before the Clinical Diagnosis of Sepsis
TLDR
New HR measures based on the empirical cumulative distribution function (ECDF) that are highly significantly associated with sepsis, but are not correlated with HR measures such as moments or sample entropy are developed.
Heart Rate Variability and Respiration Signal as Diagnostic Tools for Late Onset Sepsis in Neonatal Intensive Care Units
TLDR
The results show that alpha Slow, alpha Fast and Sample Entropy are significant parameters to distinguish S from NS and the proposed test based on optimal fusion of 6 features shows good performance with the largest AUC and a reduced probability of false alarm (PFA).
Local dynamics of heart rate: detection and prognostic implications.
TLDR
It is concluded that abnormal local dynamics of heart rate confer adverse prognosis in patients undergoing 24-h ambulatory electrocardiography.
Physiological Measurement Local dynamics of heart rate : detection and prognostic implications
TLDR
It is concluded that abnormal local dynamics of heart rate confer adverse prognosis in patients undergoing 24-h ambulatory electrocardiography.
Multiscale Entropy Analysis of Heart Rate Variability in Neonatal Patients with and without Seizures
TLDR
The findings suggest that HRV multiscale entropy analysis could be a valuable pre-screening tool for the timely detection of seizure events in newborns.
Sample Asymmetry Analysis of Heart Rate Characteristics with Application to Neonatal Sepsis and Systemic Inflammatory Response Syndrome
TLDR
It is concluded that SAA is a useful new mathematical technique for detecting the abnormal heart rate characteristics that precede neonatal sepsis and SIRS.
Improving methodology in heart rate variability analysis for the premature infants: Impact of the time length
TLDR
The linear and non-linear measurements of HRV are correlated each other and shortening the windows of analysis increased the random error for all the features and increased the bias for all but short term features and HVGs.
Trajectories of the heart rate characteristics index, a physiomarker of sepsis in premature infants, predict Neonatal ICU mortality
TLDR
Time courses of a heart rate characteristics physiomarker reveal snapshots of illness patterns, some of which were more deadly than others.

Human fetuses have nonlinear cardiac dynamics.
TLDR
It is concluded that the HR time series, in low-risk human fetuses, could not be modeled as temporally uncorrelated noise, linearly correlated noise, or static filtering of linearly correlation noise.
Nonlinear dynamics of heart rate variability in cocaine-exposed neonates during sleep.
TLDR
RRI dynamics in infants with PCE and normal controls are similar; and in both groups, sympathetic dominance during active sleep produces primarily periodic low-frequency oscillations in RRI, whereas in quiet sleep vagal modulation leads to RRI fluctuations that are broadband and dynamically more complex.

TLDR
The decreased ApEn indicates increased regularity in the FHR during hypoxia in spite of the increased variability, and may provide insight into the regulatory feedback mechanisms of the fetal heart rate during periods of Hypoxia.
Heart Rate Variability Analysis in Full-Term Infants: Spectral Indices for Study of Neonatal Cardiorespiratory Control
TLDR
Regression analysis of low frequency versus TP and RSA versus TP graphs gave strong support to the hypothesis that there were indeed two distinct patterns of HRV behavior, and may be of value in the study of cardiorespiratory control in neonates.
Physiological time-series analysis using approximate entropy and sample entropy.
TLDR
A new and related complexity measure is developed, sample entropy (SampEn), and a comparison of ApEn and SampEn is compared by using them to analyze sets of random numbers with known probabilistic character, finding SampEn agreed with theory much more closely than ApEn over a broad range of conditions.
Physiological time-series analysis: what does regularity quantify?
TLDR
This work provides a formal mathematical description of approximate entropy and provides a multistep description of the algorithm as applied to two contrasting clinical heart rate data sets, indicating the utility of ApEn to test this hypothesis.
Approximate Entropy: A Regularity Measure for Fetal Heart Rate Analysis
TLDR
Approximate entropy (ApEn), a recently developed mathematical formula quantifying regularity, was applied to fetal heart rate (FHR) data, supporting the hypothesis that extremely regular FHR patterns imply a greater likelihood of acidosis.
