"WebTypes of potassium ion channels There are 4 types of potassium ion channels involved in repolarization. These are K v 1, K v 2, K v 3 and K v 4. K v 1 Repolarization of the axon is achieved by the K v 1 channel. K v 2 Activation of the K v 2 channel is achieved more slowly in contrast to the K v 4 channels which are activated much more rapidly. " - Potassium u waves
