Determination of potassium level is one of the most frequent laboratory tests in clinical medicine. Hyperkalaemia is defined as a potassium level >5.0 mmol/L and is one of the most clinically important electrolyte abnormalities, because it may cause dangerous cardiac arrhythmia and sudden cardiac death. Here, we review methodological challenges in the determination of potassium levels, important clinical aspects of the potassium homoeostasis as well as of the pathophysiology of hyperkalaemia.
血钾水平测定是临床医学中最常见的实验室检查之一。高钾血症定义为血钾水平>5.0 mmol/L,是临床上最重要的电解质异常之一,因为它可能导致危险的心律失常和心源性猝死。在此,我们综述血钾水平测定中的方法学挑战、钾稳态的重要临床方面以及高钾血症的病理生理学。
