repolarization
[re″po-lah-rĭza´shun]1. the reestablishment of polarity, especially the return of a cell's membrane potential to resting potential after depolarization.
2. in cardiac physiology, the restoration of the cell to its maximal diastolic potential, represented by phase 0 to phase 3 of the action potential.

repolarization
Restoration of the resting polarized state in a muscle or nerve fibre. Polarization implies a balanced electrical charge on either side of the fibre membrane, being, in the resting state, negative on the inside and positive on the outside. In depolarization the charges are locally reversed.Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
