Cardiac Muscle Action Potential Diagram EXPLAINED

The video tutorial by Kevin Tokoph on Catalyst University explains the action potential of cardiomyocytes, distinct from the pacemaker potential. It covers the phases of action potential, including depolarization, plateau, and repolarization, highlighting the role of sodium, potassium, and calcium ions. The plateau phase is unique to cardiac muscle, allowing efficient blood pumping. The tutorial emphasizes the importance of understanding these phases for comprehending cardiac function.
