Discussion of Difference Equation Model of Ventricular Parasystole as an Interaction between Cardiac Pacemakers Based on the Phase Response Curve

A ventricular parasystole is a cardiac rhythm resulting from an irregular discharge of an ectopic pacemaker to the sinoatrial node (sinus pacemaker). The intrinsic cycle length of the ectopic pacemaker is influenced by the impulses of the sinus pacemaker. This influence is described by a phase response curve (PRC). The stimulus phase of a ventricular parasystole is modeled by a discontinuous difference equation developed from the PRC by Ikeda et al. This study analyzes the periodic solutions of Ikeda et al. (1983) difference equation with different phase response curves.
