This model has been curated and unit-checked and is known to run in COR and PCEnv. This variant is parameterised for the cardiac EPICARDIAL CELL.
ABSTRACT: A tetrodotoxin-sensitive persistent sodium current, IpNa, was found in guinea pig ventricular myocytes bywhole-cell patch clamping. This current was characterized in cells derived from the basal left ventricular subendocardium,midmyocardium, and subepicardium. Midmyocardial cells show a statistically significant (P,0.05) smaller IpNathan subendocardial and subepicardial myocytes. There was no significant difference in IpNa current density betweensubepicardial and subendocardial cells. Computer modeling studies support a role of this current in the dispersion ofaction potential duration across the ventricular wall."
