Hyperkalemia

Hyperkalemia is an electrolyte disorder characterized by a serum or plasma potassium concentration exceeding the normal physiological threshold, typically defined as greater than 5.0 to 5.5 mEq/L Clinical consequences stem from altered cellular membrane resting potentials, manifesting variably as muscle weakness, paresthesias, characteristic electrocardiographic abnormalities, and potentially lethal cardiac arrhythmias

Hyperkalemia is an electrolyte disorder characterized by a serum or plasma potassium concentration exceeding the normal physiological threshold, typically defined as greater than 5.0 to 5.5 mEq/L Pathophysiologically, the condition arises from reduced renal potassium clearance, transcellular shifts from the intracellular to extracellular fluid, or massive cell lysis

It predominantly affects the cardiovascular, neuromuscular, and renal systems, occurring most frequently in patients with acute kidney injury, chronic kidney disease, heart failure, diabetes mellitus, or those receiving medications that impair potassium excretion Clinical consequences stem from altered cellular membrane resting potentials, manifesting variably as muscle weakness, paresthesias, characteristic electrocardiographic abnormalities, and potentially lethal cardiac arrhythmias
