Load-dependent characteristics in the TP + M model for two initial virtual sample lengths Linit: 90% and 95%Lmax. The abscissa plots the force values normalized to the maximum isometric value Fisom corresponding to the initial length Linit. a The load dependence index (LDI) calculated as shown in Fig. 8. b Action potential duration calculated at 90% repolarization (APD90)
