Comparison between spectral analysis and symbolic dynamics for heart rate variability analysis in the rat

Abstract Spectral analysis of heart rate (HR) has been widely used to assess the autonomic cardiovascular control. A nonlinear approach, known as symbolic analysis, has been reported to be very useful to assess the autonomic control of cardiovascular system in humans, but very few studies reported o...
