This document discusses hypokalemia, defined as a serum potassium level below 3.5 mEq/L. It provides information on the electrocardiographic manifestations of hypokalemia from several references. Guidelines are given for potassium repletion via peripheral or central lines, including maximum rates of 4 mEq/hour peripherally or 40 mEq/hour centrally. Potassium levels should be monitored after 6 hours. The document emphasizes intermittent low-volume infusions or continuous high-volume infusions for potassium repletion according to the route of administration. It concludes by thanking the reader.
