Spiral dynamics induced by spatiotemporal modulation is investigated in the generic excitable Barkley model. The coexistence of meandering spiral wave and travelling spiral wave in the same medium is discovered under proper spatiotemporal modulation. The underlying mechanism behind this coexistence phenomenon is analyzed. And the two necessary conditions which are needed to observe the coexistence of meandering spiral wave and travelling spiral wave in the excitable Barkley model are discussed.
