Abstract

We investigate the dynamics of a pair of electrically coupled pacemaking sino-atrial node cells based on a physiologically detailed model. Each cell has distinguished oscillation properties. It is found that at low, yet still physiologically reasonable coupling conductance values, complex dynamics including chaos can arise. Occurrence of these complex dynamics in coupled pacemaker cells may provide an explanation for the origin of certain cardiac arrhythmias.
