Purpose of Study: The aim of this study was to characterize the central-autonomic interaction
underlying the multifractality in heart rate variability (HRV) of healthy humans. Materials and …

The influence from the central nervous system on the human multifractal heart rate variability
(HRV) is examined under the autonomic nervous system perturbation induced by the head …

Entropy-based and fractal-based metrics derived from heart rate variability (HRV) have
enriched the way cardiovascular dynamics can be described in terms of complexity. The …

The evaluation of the correlation between the activations of various organs has great
importance. This work investigated the synchronization of the brain and heart responses to …

Quantification of brain-heart interplay (BHI) has mainly been performed in the time and
frequency domains. However, such functional interactions are likely to involve nonlinear …

In this paper, we participate to the discussion set forth by the editor of Chaos for the
controversy,“Is the normal heart rate chaotic?” Our objective was to debate the question,“Is …

Objective: To characterize the multifractal behavior of the beat to beat heart-period or RR
fluctuations in fibromyalgia patients (FM) in comparison with healthy-matched subjects …

Recent research has clarified the existence of a networked system involving a cortical and
subcortical circuitry regulating both cognition and cardiac autonomic control, which is …

Detrended Fluctuation Analysis (DFA) is a popular method for assessing the fractal
characteristics of biosignals, recently adapted for evaluating the heart-rate multifractal and/or …

Nonlinear analyses of heart rate variability (HRV) can be used to quantify the
unpredictability, fractal properties and complexity of heart rate. Fractality and its analysis …
