WebLow potassium or hypokalemia is a condition where the level of potassium in the blood drops below the normal limit of 3.6-5.2 mEq/L. The symptoms of hypokalemia are usually mild and may include muscle cramps, weakness, … WebHyperkalemia is affecting the membrane potential by depolarizing it, which makes it easier for cells to reach the threshold potential, and subsequently action potential. As more cells are now capable of throwing off action potentials, autorhythmic myocytes seize the moment and fire on, creating ectopic beats and reentry tachycardias.
