Detecting nonlinearity and phase synchronization with surrogate data
  • M. Paluš, D. Hoyer
  • Mathematics, Medicine
  • IEEE Engineering in Medicine and Biology Magazine
  • 1 November 1998
Methods for detecting nonlinearity in univariate and multivariate time series and methods for identification of phase synchronization in bivariate time series are presented. Both techniques utilize… Expand

Mutual information function assesses autonomic information flow of heart rate dynamics at different time scales
TLDR
The autonomic information flow (AIF) represents the complex communication within the Autonomic Nervous System (ANS). Expand

Altered diurnal autonomic variation and reduced vagal information flow in acute schizophrenia
OBJECTIVE This study aimed to further investigate autonomic function in schizophrenic patients using long-term electrocardiographic (ECG) recordings. METHODS Twenty unmedicated patients suffering… Expand

Fetal heart rate variability reveals differential dynamics in the intrauterine development of the sympathetic and parasympathetic branches of the autonomic nervous system.
The aim of this study was to investigate the hypothesis that fetal beat-to-beat heart rate variability (fHRV) displays the different time scales of sympatho-vagal development prior to and after 32… Expand

Using Heart Rate Variability to Stratify Risk of Obstetric Patients Undergoing Spinal Anesthesia
In this study, we evaluated whether point correlation dimension (PD2), a measure of heart rate variability, can predict hypotension accompanying spinal anesthesia for cesarean delivery. After the… Expand

Mutual information and phase dependencies: measures of reduced nonlinear cardiorespiratory interactions after myocardial infarction.
The heart rate variability (HRV) is related to several mechanisms of the complex autonomic functioning such as respiratory heart rate modulation and phase dependencies between heart beat cycles and… Expand

Permutation entropy improves fetal behavioural state classification based on heart rate analysis from biomagnetic recordings in near term fetuses
TLDR
The relevance of the complexity of fetal heart rate fluctuations with regard to the classification of fetal behavioural states has not been satisfyingly clarified so far. Expand

Fetal Functional Brain Age Assessed from Universal Developmental Indices Obtained from Neuro-Vegetative Activity Patterns
Fetal brain development involves the development of the neuro-vegetative (autonomic) control that is mediated by the autonomic nervous system (ANS). Disturbances of the fetal brain development have… Expand

Drug effect on EEG connectivity assessed by linear and nonlinear couplings
Quantitative analysis of human electroencephalogram (EEG) is a valuable method for evaluating psychopharmacological agents. Although the effects of different drug classes on EEG spectra are already… Expand

Fetal development of complex autonomic control evaluated from multiscale heart rate patterns.
Development of the fetal autonomic nervous system's integrative capacity in relation to gestational age and emerging behavioral pattern is reflected in fetal heart rate patterns. Conventional indices… Expand
