The Different Mechanisms of Action Potential Propagation in the Heart
It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...

متن کاملModelling in vivo action potential propagation along a giant axon.
A partial differential equation model for the three-dimensional current flow in an excitable, unmyelinated axon is considered. Where the axon radius is significantly below a critical value R(crit) (that depends upon intra- and extra-cellular conductivity and ion channel conductance) the resistance of the intracellular space is significantly higher than that of the extracellular space, such that...
متن کاملAction Potential Propagation
In the previous notes, we described the action potential for a “point” cell, so that we could use an ODE model. Here, we consider propagation of the action potential along an axon. Consider a system in which the intracellular and extracellular spaces are separated by a cell membrane. Let x be the one-dimensional spatial coordinate, and consider current conservation in the intracellular region c...
