Figure 7. USMC model modification with incorporation of KCNQ1, KCNQ4, KCNQ5 and hERG currents.

Figure 7

A, Effect of I K1 being partially replaced by a combination of I KCNQ1 (Inline graphic KCNQ1 =  0.0032 nS pF−1), I KCNQ4 (Inline graphic KCNQ4 =  0.024 nS pF−1) and I hERG (Inline graphic hERG =  0.08 nS pF−1). Note that I b has been replaced with I KCNQ5 (Inline graphic KCNQ5 =  0.016 nS pF−1). With this configuration, long-duration bursting APs were induced (left panel) while the whole cell K+ currents (middle panel) and the I-V relationships (right panel) matched the experimental data [44] (© Wang et al., 1998). B. Summary of the electrogenic components of the modified USMC model.
