the return to resting polarity of the cell membrane that has been depolarized
the process by which the heart is restored to its resting position.
The recovery process of excitable tissue following depolarization. Ventricular repolarization is represented on the ECG by the T wave; atrial repolarization is not usually visible on the ECG since it gets obscured by the simultaneously occurring QRS complex. Repolarization may also be described as the cell potential returning to its resting value.
The restoration of electrical polarity via an increase in ion differential between the cell membranes of the myocardium. It is necessary in preparation for the next heart beat
In neuroscience, repolarization refers to the change in membrane potential that returns the membrane potential to a negative value after the depolarization phase of an action potential has just previously changed the membrane potential to a positive value. Repolarization results from the movement of positively charged potassium ions out of the cell. Typically the repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting potential.
