Triggered Initiation of Retrograde Wave Propagation in a Cable of FitzHugh-Nagumo Cells

摘要

We studied a triggered initiation of retrograde propagation of an action potential in a one-dimensional cable of FitzHugh-Nagumo models. The triggered events occurred in the phase-dependent manner. A single stimulation induced alternation in action potential duration at the peripheral part of the pacemaker elements. The retrograde propagation automatically stopped.
