Individually contracting cardiomyocytes mechanically linked by an extracellular matrix belong to the class of viscoelastically coupled excitable oscillators. They exhibit an interesting range of synchronization patterns due to the interplay of autonomous oscillation and refractory period following an excitation, together with the delay introduced by the viscoelaticity. We study numerically the synchronization patterns occuring in mechanically coupled excitable oscillators depending on the viscoelastic properties of the coupling matrix.
