The effective-refractory period present during Phase 2 of the action potential of ventricular myocytes: A)is relatively long because the Na+ current does not inactivate. B) is relatively long because K+ current is immediately activated once membrane potential becomes positive. C) prevents tetanus in the heart. D) is about twice as long as in skeletal muscle
