title: Electrocardiographic changes in combined electrolyte depletion.
abstract: Cardiac action potential is affected by extracellular gradients in potassium, calcium, and magnesium with resultant electrocardiographic changes varying from subtle findings to marked repolarization abnormalities. This report presents marked electrocardiographic changes resulting from a combination of electrolytes depletion in a patient with bulimia and anorexia nervosa.
