Nonlinear Oscillations in the Conduction System of the Heart – A Model
Conference paper
Abstract
The effects of the interaction of the phase space trajectory of a modified van der Pol oscillator with a hyperbolic saddle are discussed. It is shown that the refractory period is obtained and that the saddle affects the way the model reacts both to parameter change and to external perturbation. We obtain results comparable to effects observed in recordings of heart rate variability.
