Table 1.

Conductance scaling factors for the original and optimized IKr-dynamic O'Hara-Rudy models (original and optimized IKr-dyn ORd): current conductances of the rapid (IKr) and slow (IKs) rectifier potassium current, inwardly rectifying potassium current (IK1), L-type calcium current (ICaL) and late sodium current (INaL) in the model are multiplied by the corresponding scaling factor.

Scaled currents	Original IKr-dyn ORd model	Optimized IKr-dyn ORd model
IKr	0.9	1.013
IKs	1.0	1.870
IK1	1.0	1.698
ICaL	1.0	1.007
INaL	1.0	2.661

Note that the IKr conductance in the original IKr-dyn ORd model was scaled as described in Li et al. (2017).
