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
