Abstract Summary
Human induced pluripotent stem cell-derived cardiomyocyte (hiPSC-CM) tissue consists of heterogeneous CMs coupled by gap junctions. Electromechanical effects of these couplings are estimated using a computer model. Simulations suggest that the electromechanical variability in the tissue is decreased by gap junctional couplings depending on the conductance and the number of different CMs.
