Hyperkalemia is defined as a serum potassium concentration greater than approximately 5.0-5.5 mEq/L. Hyperkalemia can be difficult to diagnose clinically because symptoms may be vague or absent; many individuals are asymptomatic. When present, symptoms are nonspecific and predominantly related to muscular or cardiac function, the most common of which are weakness and fatigue.
