Ror2 = Transverse resistance of the interstitial space between the parallel chains. Ror = Radial resistance at the surface of the bundle. Rol = Longitudinal resistance at the surface of the bundle. Cj = Capacitance of junctional membranes. Cs = Capacitance of the surface membranes. EK = Potassium equilibrium potential. ENa = Sodium equilibrium potential. ECa = Calcium equilibrium potential. RK(surf) = Potassium resistance of the surface membrane units. RK(junc) = Potassium resistance of the junctional membrane units. R'Na (surf) = Sodium resistance of the surface membrane during excitation. R'Na (junc) = Sodium resistance of the junctional membrane during excitation. R'Ca (surf) = Calcium resistance of the surface membrane during excitation. R'Ca (junc) = Calcium resistance of the junctional membrane during excitation.
