Guinea Pig Ventricular IKrWT-CR01-SM

Simucore Model Based Upon: Clancy-Rudy Markovian Model of Wild-Type IKr Channels in a Cardiac Ventricular Cell, 2001; v. 1.4


Example action potential (BCL = 400 ms).
Example action potential (BCL = 400 ms).

This model simulates guinea pig ventricular action potentials. The orignal Hodgkin-Huxley type formulation of the rapid component of the delayed-rectifier potassium current (IKr) was replaced with the Markovian one. It includes three closed states (C3, C2 and C1), an open, conducting state (O), and a single inactivation state (I).

Abstract excerpt: "We developed Markovian models of wild-type (WT) and mutant I(Kr) channels and incorporated these models into a comprehensive model of the cardiac ventricular cell."
