Abstract
We used our recently developed membrane model to calculate the dependence of propagation speed on shifts in the membrane's current-voltage (I-V) relation caused by changes in the ionic environment. These shifts can be linked analytically to changes in the concentrations of cations such as Ca++ and H+. We calculated the propagation speed using the reaction-diffusion equation for the membrane potential and obtained a value of 55 cm/s for myocardium at standard ionic concentrations. This value varied between 12 cm/s and 85 cm/s for shifts between +46 mV and -14 mV, respectively.
