摘要：Maintenance of potassium balance is a key aspect of electrolyte homeostasis. Potassium is the major intracellular cation, and its transport in the kidneys is tightly regulated. Disruptions in potassium balance, such as severe hyperkalemia ([K+] > 8 mEq/L), can lead to cardiac abnormalities that may progress to ventricular fibrillation if untreated. A diagnosis of hyperkalemia needs to be further contextualized in order to have clinical significance.
