WebApr 9, 2007 · At a normal heart rate of 60 bpm, the action potential duration (APD) of the Courtemanche model is too long (>280 ms). This is mainly due to the maximum conductance of the inward rectifier K + current being too small (g K1 =0.09 nS/pF). 4 The small value of g K1 yields a high-input membrane resistance (≈174 MΩ).
