A local phase compress scheme is applied to suppress spiral and spatiotemporal chaos in the Fitzhugh-Nagumo and Panfilov systems. In the numerical investigation, the compress signal is limited to a small area in order to control the global spiral and spatiotcmporal chaos with or without noise. The simulation shows that the system becomes homogeneous stable within a few of 50 time units. A practical control of defibrillation and pattern formation is discussed.
