Abstract
We study the dynamics of hypermeander of a spiral wave produced by the FitzHugh-Nagumo model, and use the surrogate test method to identify the irregular time series of the core position as chaotic. The correla tion dimension, and maximum Lyapunov exponent of this time series are estimated.
