Abstract

The heart rate fluctuations change from seeming irregularity in normals to more regularity during functional blockades. We investigated the prediction error of original and surrogate data in phase space and a corresponding nonlinear time series model using an artificial neural network. Particular nonlinear time structures could be found in different states
