Abstract
Viscoelastically coupled excitable oscillators are used to model individually beating spatially separated
cardiomyocytes surrounded by an extracellular matrix (ECM). We investigate how mechanical coupling via the
ECM can synchronize two such oscillators with excitation contraction coupling and electromechanical feedback
and how this synchronization depends on the rheological properties of the ECM. Extending our study to a linear
chain of coupled oscillators we find a transition to synchronization as the ECM becomes stiffer. In the case of
purely elastic coupling we observe antiphase chimera states.
