Some considerations on the IPFM model for the heart rate variability analysis

The arch or inverted arch signals are characterizing patterns of the Respiratory Sinus Arrhythmia. The ability of any model in generating these patterns can be a good criteria for their selection. We show that using the tidal volume signal as the input of the model, an alternative to the IPFM can be proposed. The relevance of our model is shown with synthesized and real signals.
