'''Potassium''' is an electrolyte symbolized with the letter K. When '''potassium''' is low, everyone freaks out; a condition called [[Hypokalemia|hypokalemia]]. When '''potassium''' is high, everyone freaks out again; a condition called [[Hyperkalemia|hyperkalemia]]. Hyperkalemia can cause life-threatening arrhythmia in both patients (by affecting depolarization) and health care providers (by scaring the bejeezus out of them).
