Effects of Epinephrine on the Pacemaker Potassium Current of Cardiac Purkinje Fibers
Epinephrine promotes spontaneous activity in cardiac Purkinje fibers through its action on the pacemaker potassium current (i (K(K2))). The mechanism of the acceleratory effect was studied by means of a voltage clamp technique. The results showed that the hormone speeds the deactivation of i (K(K2))...
