"This paper presents some results coming from continuous, non-linear modelling of heart rate (HR) complex behaviour caused by various neural control regimes vagal control capability to modify the complexity of HR variability is manifested. This model is believed to reveal more about importance of the delays of fast beat-by-beat vagal baroreflex control feedback influences and displays development of chaotic behaviour similar to the one observed in other, even much simpler, non-linear systems where the deterministic chaos develops such as through bifurcations, for example. The paper briefly describes features of the modelling method leading to complex behaviour of the cardiovascular system from periodic-like R-R diagrams to ones with high dimension of deterministic chaos. The correlation dimension and largest Lyapunov exponents were calculated for measured data and briefly compared to the ones calculated for real cardiac disorder signals." . .
