Courtemanche-Ramirez-Natel Model for Human Atrial Cells - One Cell

Human Ayrial Cell, 1998

This model is used to simulate the activation of human atrial cells using the model of Marc Courtemanche, Rafael J. Ramirez and Stanley Nattel, 1998, American Journal of Physiology, 275, H301-H321. Using the applet, the myocyte can be paced at various cycle lengths and the final APD and DI calculated automatically. In addition, it is possible to visualize the currents, gate variables, and ionic concentrations.

N(S1's) indicates how many S1 stimuli to apply.

S1 (bcl) indicates the cycle length for the S1 stimuli.

S2 (bcl) indicates the cycle length for the S2 stimulus.

Click "Start" to start the simulation. Use "Replot" to replot on the screen once a check box has been selected or a new value has been entered for S1, S2 or N. Use "plot Currents" to plot the various currents of the model.
