In this course, we teach you the basic physiological mechanisms regulating potassium concentration in the body fluid compartments. Abnormalities of extracellular fluid potassium concentration are common and in the absence of intervention are potentially lethal. We will teach you a simple approach to remembering the extensive differential of hypokalemia and hyperkalemia. This approach is based on a knowledge of the basic physiology of potassium homeostasis in the body. You will learn the clinically important ECG manifestations of hyperkalemia.
