Two components of cardiac delayed rectifier K+ current. Differential sensitivity to block by class III antiarrhythmic agents
An envelope of tails test was used to show that the delayed rectifier K+ current (IK) of guinea pig ventricular myocytes results from the activation of two outward K+ currents. One current was specifically blocked by the benzenesulfonamide antiarrhythmic agent, E-4031 (IC50 = 397 nM). The drug-sensi...
