However, with prolonged depolarization, the cell membrane will become more refractory and less likely to fully depolarize. The following signs and symptoms should raise the concern for hyperkalemia: Cardiac manifestations: -Peaked T waves.
Does hyperkalemia affect depolarization?
In the setting of hyperkalemia, the resting membrane potential may change to a new level (that is, −80 mV), so that now only 5 mV of depolarization must occur before reaching the threshold potential of −75 mV.

What causes hyperkalemia?
