Abstract

Hyperkalemia is a common adverse effect of treatment for heart failure and is associated with high mortality and morbidity. The cardiac manifestations of hyperkalemia include various electrocardiogram changes. We describe a case of a 74-year-old woman with heart failure and permanent atrial fibrillation who reverted to normal sinus rhythm during recovery from hyperkalemia.

Figure

• 

  Fig. 1 The electrocardiogram performed prior to admission was atrial fibrillation at a rate of 92 bpm.

• 

  Fig. 2 The electrocardiogram performed on admission revealed Junctional bradycardia at a rate of 35 bpm and QRS duration of 136 milliseconds (K+: 8.3 mEq/L).

• 

  Fig. 3 The electrocardiogram performed on hospital day 2 showed sinus bradycardia at a rate of 53 bpm and QRS duration of 80 milliseconds (K+: 5.3 mEq/L).
