A new nonlinear model for generating RR tachograms

Using a mathematical model to produce the time series for heart rate variability (HRV) is needed to produce artificial electrocardiogram (ECG) signals. In this paper, we incorporate into our model the effects of both respiratory sinus arrhythmia (RSA) and Mayer waves. In addition, the inter-coupling between sympathetic and parasympathetic systems is also included.
