Bursting electrical activity of the model and comparison with experimental data. (A) Simulated bursting action A Inset: experimental data of bursting AP from Bengtsson et al.22. (B) Simulated staircase-like calcium transient generated by bursting APs. B Inset (centre): the stimulus applied during this simulation, −0.4 pA pF−1 for a duration of 5 s. B Inset (right): experimental data from Shmygol et al.28. (C) Computed results of four principal currents: L-type calcium, sodium and voltage gated potassium currents (IK1 and IK2) during the time course of bursting APs. (D) Simulated total contractile force of the cell model. D Inset: experimental data from Zafrah and Alotaibi32.
