Cardiac Action Potential Phases
Exploring the phases of the action potential in cardiac myocytes, including sodium channel inactivation and potassium channel opening in phase one, calcium and potassium balance in phase two, multiple potassium channels in phase three, and restoration of resting potential in phase four. Comparing fast response and slow response action potentials in pacemaker cells, discussing differences in membrane potential and ion channels. Delving into the activation of potassium and L-type calcium channels in phases zero and three, highlighting differences in conduction velocity and refractory periods.
