Abstract

As a model for RR-interval time series, a nonstationary linear Langevin equation is used. Approximating the time-dependent point of equilibrium by a piecewise constant function, an algorithm is presented to reconstruct the amplitudes of this trend. From these quantities a measure of activity is defined, which is shown to be an indicator of a deterioration of cardiac performance such as involved by congestive heart failure.
