What are the Two Phases of the Ventricular Action Potential

Question

What are the two phases of the ventricular action potential (cardiac impulse)?
A) Systole and diastole
B) Filling and ejecting
C) Depolarization and repolarization
D) P wave and T wave

Accepted Answer

The two phases of the ventricular action potential are depolarization and repolarization. The depolarization phase is when the cardiac muscle cell becomes positively charged, causing contraction of the ventricles. The repolarization phase is when the cell returns to its resting state, allowing for relaxation of the ventricles.
