include the resulting decreased internal K⁺ concentration, the increased external K⁺ concentration, norepinephrine release and acidosis. When myocardial cell are exposed to hyperkalemia, the maximum diastolic potential is depolarized as a result of the alteration of Ik1 potassium current, whose intensity and direction is strictly dependent on intracellular and extracellular potassium concentrations. With Ik1 suppressed, an hyperpolarizing effect is lost and therefore there can be activation of funny current
