21
Q

The action potential in cardiac cells is divided into 5 phases, which include:

  • Phase 0: a fast upstroke from the spontaneous increase in Na permeability
  • Phase 1: partial repolarization from the activation of Na+ channels & leaking of K+
  • Phase 2: plateau from the opening of calcium channels & outward leaking of K+
  • Phase 3: spontaneous depolarization from gradual increase in Na permeability
  • Phase 4: repolarization from opening of potassium channels
A

Phase 0: a fast upstroke from the spontaneous increase in sodium permeability
