•We propose autoregressive process in a mathematical model based on coupled differential equations in order to model electrocardiogram signals.•We compare our results with experimental tachogram by means of Poincare plot and dentrended fluctuation analysis.•Our results have showed that the model with autoregressive process exhibits good agreement with experimental measures from tachogram generated by electrical activity of the heartbeat.•With the tachogram we build the electrocardiogram by means of coupled differential equations.
