Cable properties and propagation velocity in a long single chain of simulated myocardial cells

摘要

BackgroundPropagation of simulated action potentials (APs) was previously studied in short single chains and in two-dimensional sheets of myocardial cells [-]. The present study was undertaken to examine propagation in a long single chain of cells of various lengths, and with varying numbers of gap-junction (g-j) channels, and to compare propagation velocity with the cable properties such as the length constant (λ).
