144794 - A Novel Model for Heart Beating Rhythms 

In this paper, an improved model of cardiac conduction system with consideration of main pacemakers and heart muscles is investigated. The pacemakers consist of Sinoatrial node, atrioventricular node and His-Purkinje are simulated through three modified van der Pol oscillators with time delayed velocity coupling. The atrial and ventricular muscles are modeled by four modified Hindmarsh-Rose (HR) neuron systems stimulated by pacemakers. The synthetic electrocardiogram (ECG) constructed through a combination of electric signals of atrial and ventricular muscles.  An implicit mapping topology for the complex cardiac firing is established. A specific Poincare section is defined to predict the waveform bifurcations varying with a system parameter the corresponding stability is defined by eigenvalue analysis. The cardiac firing results are presented to provide the normal and pathological rhythms in the cardiac conduction system. The presented study provides a new perspective in exploring the nonlinear dynamics of heart beating.
