    Effects of fetal respiratory movements on the short-term fractal properties of heart rate variability

    We evaluated the effect of fetal respiratory movements (RM) on the heart rate (HR) fractal dynamics.Abdominal ECG recordings were collected from low-middle-risk pregnant woman at rest. Mean gestational age was...

    Applying fractal analysis to short sets of heart rate variability data

    The aim of this study was to explore the interchangeability of fractal scaling exponents derived from short- and long-term recordings of real and synthetic data. We compared the α1 exponents as obtained by detren...

    Application of empirical mode decomposition to heart rate variability analysis

    The analysis of heart rate variability, involving changes in the autonomic modulation conditions, demands specific capabilities not provided by either parametric or non-parametric spectral estimation methods. ...
