This model is according to the paper Cellular consequences of HEGR mutations in the long QT syndrome: precursors to sudden cardiac death. The author used Markovian model of cardiac Ikr in the paper. Figure4B in the paper has been reproduced using CellDesigner3.5.1. The cell is depolarized to the indicated test potential for 250ms (from 50ms to 300ms) from a holding potential of -40mV and then repolarized to -40mV. Change the value for vtest from -30,-20,-10,0,10,20,30,40 for each simulation in order to produce the different cureve in the paper.
