摘要：

We study numerically the effects of high-frequency stimulation in excitable cardiac tissue with an inexcitable obstacle using a Fitz-Hugh Nagumo type model. We show that if the frequency of stimulation is sufficiently high and the size of the inexcitable obstacle is sufficiently large, then a re-entrant pattern can be initiated. We also show that with overdrive stimulation a re-entrant pattern can be removed provided there are no obstacles at which new re-entrant patterns are created. © 1993 Academic Press Limited.
