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. However, the fact that hyperkalemia can lead to sudden death from cardiac arrhythmias requires that physicians be quick to consider hyperkalemia in patients who are at risk for it.
