This work presents a new method using time-varying autoregressive modelling for the assessment of heart rate signals stationarity in patients before the onset of ventricular tachyarrhythmias, including comparison with a control group. A general stationarity trend is reported for all subjects, and particularly no significant change is observed before an arrhythmic event. Evaluation of the model fitting performed by a hypothesis test suggests the presence of nonlinearities.
