A class of intermittent feedback scheme is proposed to eliminate the spiral wave in the excitable media, which is described by the Fitz-Hugh-Nagumo equation. The activators of the sites is observed and compared with the selected threshold (less than the maximum activator), a negative feedback is imposed on the whole system by inputting linear negative variable into the equation only when the sampled activator exceeds the threshold. It is found that the spiral wave is easier to be removed and the whole media becomes homogeneous when all the sites are monitored and smaller threshold is used, and the spiral wave just becomes sparse and breakup of spiral wave can be observed when the threshold is not small. On theother hand, weaker intensity of feedback still causes the spiral wave to be removed and the whole media still can become homogeneous when only one site is monitored. The controller will stop working as the whole media become homogeneous synchronically.
