In this paper, a modified van der Pol oscillator equation is considered whichappears in several heart action models. We study its global dynamics and verifymany interesting bifurcations such as a Hopf bifurcation, a heteroclinic saddleconnection, and a homoclinic saddle connection. Some of these bifurcations aredetected by using Conley index methods. We demonstrate how the study ofconnection matrices and transition matrices shows how to select interestingparameter values for simulations.
