Does oral potassium supplementation reduce QT dispersion in young women with anorexia nervosa?
Does oral potassium supplementation reduce QT dispersion in young women with anorexia nervosa?
Oral potassium supplementation significantly reduces QT dispersion in patients with anorexia nervosa, suggesting that potassium depletion is a critical factor driving repolarization abnormalities in this population.
No takes yet. Share an insight, caveat, or question.
May support potassium repletion to lessen repolarization abnormalities in anorexia nervosa; hypothesis-generating and requires randomized confirmation before practice change.
Franzoni et al. (2002) studied this question.
