Entropy, as it relates to dynamical systems, is the rate of information production. [] Key Method We have also evaluated cross-ApEn and cross-SampEn, which use cardiovascular data sets to measure the similarity of two distinct time series. SampEn agreed with theory much more closely than ApEn over a broad range of conditions. The improved accuracy of SampEn statistics should make them useful in the study of experimental clinical cardiovascular and other biological time series.

Cardiac variability time-series analysis by sample entropy and multiscale entropy

It is demonstrated that SampEn is small for higher values of tolerance r and is able to distinguish different physiologic time series with tolerance level r, and this traditional algorithm exhibits higher complexity for pathologic subjects than for healthy physiologic subjects, which is misleading observation.

Time series derived from simpler systems are single scale based and thus can be quantified by using traditional measures of entropy. However, times series derived from physical and biological systems

Evaluation of physiologic complexity in time series using generalized sample entropy and surrogate data analysis.

A method for complex system analysis based on generalized statistical formalism and surrogate time series is proposed and discussed, which shows that, for nonperiodic signals, qSDiff curves have a maximum point (qSDiff(max)), and suggests a potential use for chaotic system analysis.

Measuring the Complexity of a Physiological Time Series: a Review

Most popular complexity estimators (entropies) applied in biological, medical, sport and exercise sciences and their performances are reviewed and new approaches and solutions remain on the agenda.

Quantification of regularity in RR-interval time series using approximate entropy, sample entropy, and multi-scale entropy

A general decrease in entropy in subjects with congestive heart failure is suggested, based on the results of this study.

Phase entropy: a new complexity measure for heart rate variability

A new entropy method, phase entropy (PhEn), has been proposed as a quantification of two dimensional phase space that quantifies the multiplicity and rate of variability associated with the physiological signals and is sensitive to time-irreversibility.

Distribution Entropy (DistEn): A complexity measure to detect arrhythmia from short length RR interval time series

Results show that DistEn shows a promising behavior as bio marker for detecting Arrhythmia from short length RR interval data, and undoubtedly exhibits a consistently high performance as a classification feature in comparison with ApEn and SampEn.

Physiological time-series analysis: what does regularity quantify?

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 (ApEn) as a complexity measure.

Approximate entropy (ApEn) is a recently developed statistic quantifying regularity and complexity, which appears to have potential application to a wide variety of relatively short (greater than 100

Approximate entropy offered no advantage over measurement of short-term FHR variation antepartum or in labor, and neither measurement predicted outcome in labor.

Results indicate that the entropy of R-R intervals reflects parasympathetic modulation of heart rate, which is directionally similar to changes in SDNN and HF norm.

Probing the Order within Neonatal Heart Rate Variability

It is concluded that neonatal RR interval time series are ordered by periodic processes with frequencies over a large range, and that the extent of order is less during illness when HRV is low.

Hemispheric and medullary brain stem infarctions seem to damage the cardiovascular autonomic regulatory system and appear as abnormalities in the magnitude of HR variability, which can be more easily detected with the use of analysis methods of HR volatility, which are based on moment statistics, than by methods based on nonlinear dynamics.
