Quantifying heart rate dynamics using different approaches of symbolic dynamics
The analysis of symbolic dynamics applied to physiological time series is able to retrieve information about dynamical properties of the underlying system that cannot be gained with standard methods like e.g. spectral analysis. Different approaches for the transformation of the original time series to the symbolic time series have been proposed. Yet the differences between the approaches are un...
متن کاملMixing Dynamics of Heart Rate Variability
The theoretical Erlang distribution of the k –fold Poincaré return time of a mixing dynamical system is a very good fit of the experimental RR histograms of normal subjects. From this perspective, a heartbeat is emitted when the state of the attractor has returned k consecutive times to some finite region of the phase space of an abstract dynamical system that generates the RR sequence. The hig...
متن کاملSymbolic dynamics of heart rate variability: a probe to investigate cardiac autonomic modulation.
BACKGROUND Sympathetic and parasympathetic systems are considered the principal rapidly reacting systems that control heart rate. METHODS AND RESULTS We propose a symbolic analysis series to quantify the prevalence of sympathetic or parasympathetic cardiac modulation. This analysis decomposes the heart rate variability series in patterns lasting 3 beats and classifies them into 3 categories: ...

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...
