  • hyperkalemia, a common life-threatening metabolic emergency - in renal failure;
  • hyperkalemia, and lethargy or weakness - as sole manifestations;
  • increasing potassium levels, associated - with depressed electrical conduction;
  • mild levels of hyperkalemia, and acceleration - of terminal repolarization, T wave changes;
  • wide QRS complex rhythm - with sine wave configuration;
  • management of patient with hyperkalemia - therapies, aimed at stabilization of myocardium;
