1. A method for the predictive calculation of a cardiac signal course, comprising the following process steps: providing for scanning values by scanning of a time progression of a cardiac signal during a certain scanning period, calculation of model coefficients according to a 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 a last predicted signal value as a last scanning value during the autoregressive modeling.
