Hyperkalemia is a common cause of electrolyte induced cardiac conduction disturbance. A well-defined series of changes at the cellular level leads to characteristic evolutionary changes in the surface electrocardiogram. Initial high T waves and shortened intervals give way to prolongation of conduction and lethal dysrhythmias as the serum potassium level rises. The patterns of electrocardiographic changes associated with hyperkalemia are reviewed and an outline of appropriate therapeutic interventions.
高钾血症是电解质诱导的心脏传导障碍的常见原因。细胞水平上一系列明确的变化会导致体表心电图出现特征性的演变。随着血清钾水平升高，最初高耸的T波和缩短的间期会被传导延长和致命性心律失常所取代。本文回顾了与高钾血症相关的心电图变化模式，并概述了适当的治疗干预措施。
