A pure and single K+ current of ultrarapid delayed rectifier K+ current or transient outware K+ current is respectively expressed on Xenopus Oocytes. This is a moderm pharmacological model for evaluation class Ⅲ antiarrhythmiv durgs, overcomes many defcts such as lacking human fresh cardiac muscle cells as material and co-expression of many currents on cell membrane. A new compound A1998 from Ocean material is evaluated in this model for class Ⅲ antiarrhythmic functions.
