Abstract
In this paper we explore a new method for constructing phase space from time series of heart beats for using the nonlinear model of chaotic time series to analyze HRV signal. We explore whether it is unreasonable to directly reconstruct the phase space from the RR intervals. A new method is proposed to reconstruct the phase space from a derived time series using filtered delay coordinate map. The method is applied to clinical cases
