Electrical Charge Positive Processes Mechanical Contraction Heart Depolarization

Front What are the two electrical processes associated with the mechanical contraction of the heart?
Back These are:
1) depolarization, when the electrical charge on the muscle cell surface changes from positive to negative.
And,
2) repolarization, when the heart returns to its resting state and positive charge is restored to the surface.
