Title Effect of coupling strength on the beating rate in excitable cardiac cell culture
Abstract Variation in heart beating rates during the development of cell connections and synchronized beating had been observed in experiment[1]. This phenomenon can be reproduced in a model of coupled excitable FitzHugh Nagumo elements in the presence of noise. In some coupling regimes, the beating rate can be enhanced up to 60% in our simulations, as observed in experiments. The variation of the beating rate can be explained qualitatively by Kramers’ escape rate in a single potential well model. [1] "Synchronization in growing heterogeneous media", W. Chen, S. C.
