Title: Driven nonlinear oscillators for modeling cardiac phenomena. 11 p., fig.
Language: English
ABSTRACT. A model of cardiac transmembrane action potential
excitation and propagation is presented. The model consists of
strongly asymmetric van der Pol oscillators and novel quiescent
nerve pulse equations modeling cardiac pacemakers and conducting
tissues, respectively. A detailed analysis of bifurcation
structures of driven nerve pulse equations given. The rich
variety of calculated arrhythmias and conduction blocks agrees
well with measured behavior of animal cardiac Purkinje fibres.
