Contractions of ENDO (left) and EPI (right) cells under a high (isometric) and low loads (at afterload of 20, 40, 60, and 80% of maximal isometric force F max) at isotonic mode of contractions. Tension (F) developed by cells (top panel) and cell deformations (bottom panel, ΔL in  % of the initial length L 0) during the cardiac cycle in ENDO and EPI models. The stimulus was applied at 60 ms
