Hyperkalemia was associated with complete heart block in one patient that resolved by first showing right anterior hemiblock). Then the right bundle branch block resolved, leaving the marked left axis deviation that was present before the hyperkalemic episode. Another patient with hyperkalemia had right bundle branch block with marked left axis deviation, both of which disappeared with correction of the hyperkalemia. These findings suggest that hyperkalemia can depress conduction in the His-Purkinje system and raise the possibility that hyperkalemia may induce complete heart block distal to the atrioventricular junction.
高钾血症与一名患者的完全性心脏传导阻滞相关，该患者最初表现为右前分支阻滞，随后右束支传导阻滞消失，仅遗留高钾血症发作前就已存在的显著左轴偏移。另一名高钾血症患者出现右束支传导阻滞伴显著左轴偏移，高钾血症纠正后二者均消失。这些发现提示，高钾血症可抑制希氏-浦肯野系统的传导，并增加高钾血症可能诱发房室结远端完全性心脏传导阻滞的可能性。
