In severe cases, hypokalemia can lead to dangerous disturbances in heart rhythm (dysrhythmia). WebDefinition and Causes. Hypokalemia occurs when the serum potassium concentration is less than 3.5 mEq/L (normal range 3.5 to 5.5 mEq/L). The general causes of hypokalemia are (1) disorders of internal balance and (2) disorders of external balance. The clinical conditions most commonly associated with each of these are provided in Box 51-1.
