Change in APD90 in response to varying drug kinetics of block

AP simulations were run with rates calculated from 22°C and 36°C experimental data or with scalars applied to 22°C calculated rates. The change in APD90 is expressed as the difference between AP data in the presence and absence of drug under the listed conditions.
