Summary
Serum sodium (Na) concentration is mediated by free water intake, circulating levels of antidiuretic hormone (ADH) and renal filtration of sodium. Disorders of potassium, especially hyperkalemia, are the most feared electrolyte disorders due to their ability to cause life-threatening cardiac arrhythmia. Release of calcium stores into the circulation is regulated by extracellular calcium concentration, parathyroid hormone (PTH), vitamin D metabolites and calcitonin. Magnesium is one of the most abundant cations in the body and plays a large role in cardiac contractility as well as nerve conduction.
