Abstract

A new formulation of potassium channel gating processes with the Markov representation for utilizing in the action potential (AP) mathematical models, is presented. In contrast to the Hodgkin's and Huxley's (H-H) representation, the Markovian representation provides interdependence of channel gating processes, which is closer to reality. This also allows the simulation of structural changes of channel proteins by implementing the corresponding modifications in the channels' kinetics. In computer simulation, it is observed that single early-after depolarizations (EAD) appear in the AP of wild-type myocardial cells with the Markovian representation of the IKr channels.
