Viscoelastically coupled excitable oscillators are used to model individually beating spatially separated cardiomyocytes surrounded by an extra-cellular matrix (ECM) of collagen. This corresponds to the early states in the development of engineered heart muscle (EHM). Synchronization of the beating of the cardiomyocytes is necessary for functioning of EHM. We investigate how mechanical coupling via the ECM can synchronize two excitable oscillators with excitation contraction coupling and electromechanical feedback and how this synchronization depends on the rheological properties of the ECM.
