repolarization /re·po·lar·iza·tion/ (re-po″ler-ĭ-za´shun) the reestablishment of polarity, especially the return of cell membrane potential to resting potential after depolarization.

re·po·lar·i·za·tion (r -p  l r- -z  shn)n. The restoration of a polarized state across a membrane. |
repolarization
[rēpō′lərīzā′shən]
Etymology: L, re + polus, pole; Gk, izein, to cause
the process by which the membrane potential of a neuron or muscle cell is restored to the cell's resting potential. In a cardiac muscle cell, the repolarization process begins after phase 0 of the action potential and is completed by the end of phase 3. It encompasses the effective and relative refractory periods and correlates with the Q-T interval on the electrocardiogram. See also cardiac action potential.
repolarization
the re-establishment of polarity, especially the return of cell membrane potential to resting potential after depolarization.
