Hyperkalemia

Elevated blood potassium. Potassium is the major positive ion (cation) found inside of cells. The chemical notation for potassium is K+. The proper level of potassium is essential for normal cell function. An abnormal increase (or decrease) of potassium can profoundly affect the nervous system and heart, and when extreme, can be fatal. The normal blood potassium level is 3.5 - 5.0 milliEquivalents/liter (mEq/L), or in international units, 3.5 - 5.0

hy·per·ka·le·mia (hi″pər-kə-leґme-ə) [hyper- + L. kalium potassium + -emia] abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves, depressed P waves, and wide QRS complexes, eventually with atrial asystole). In severe cases, weakness and flaccid paralysis may occur. Called also potassemia and hyperpotassemia. hyperkalemic adj
