Model Structure

In 1980, Lisa Ebihara and Edward A. Johnson published the first electrophysiological model to specifically target a single ion channel and attempt to quantify its parameters. They used the Hodgkin-Huxley formulation to revise the parameters of the fast sodium current in cardiac muscle. This model exhibits a faster sodium current than the Beeler-Reuter model, and when the two models are coupled, the Ebihara-Johnson can be used as a direct replacement of the sodium kinetics of the Beeler-Reuter.
