Limit cycle APs for extreme initial conditions for the TTP06 model (A) and for the ORd-CiPA model (B). Extreme Γ₀ values covering approximately 44 mM are computed from the extreme ${[{\mathrm{K}}^{+}]}_{\mathrm{i}}$ and ${[{\text{Na}}^{+}]}_{\text{i}}$ observed in human ventricular models, as reported in Figure 4.
