Abstract
A method for the predictive calculation of a cardiac signal course incorporates the following process steps:scanning of the time progression of a cardiac signal during a certain scanning period,calculation of model coefficients according to the method of autoregressive modeling from the scanning values of the scanning period,predictive calculation of anticipated signal values following the scanning period during a prediction period according to the method of autoregressive modeling based on the scanning values and model coefficients, with the signal values calculated iteratively, in each case by entering the last predicted signal value as the last scanning value during the autoregressive modeling.
