Kv4.3, Kv1.4 encoded K(+) channel in heart cells (Greenstein et al 2000) (XPP)

A model of canine I:(to1) (the Ca(2+)-independent transient outward current) is formulated as the combination of Kv4.3 and Kv1.4
currents and is incorporated into an existing canine ventricular myocyte model. Simulations demonstrate strong
coupling between L-type Ca(2+) current and I:(Kv4.3) and predict a bimodal relationship between I:(Kv4.3)
density and APD whereby perturbations in I:(Kv4.3) density may produce either prolongation or shortening of APD,
depending on baseline I:(to1) current level.
