Abstract
A mathematical model composed by three-coupled nonlinear oscillators coupled by time-delayed connections is used to investigate randomness effects on heart rhythm analysis. Accordingly, delayed-differential equations represent heart dynamics. Nondeterministic aspects are contemplated considering random connections among oscillators. The main idea is to show that nonlinearities and randomness define together the great variety of possibilities of heart dynamics. In general, results show that the model is able to capture the main behaviors of the cardiac system and that pathological behavior can evolve from normal rhythms due to random variation.
