Structured PICO

Does oral potassium supplementation reduce QT dispersion in young women with anorexia nervosa?

Population

68 young women, comprising 28 with anorexia nervosa (self-induced starvation), 20 thin women, and 20 normal-weight women (body mass index <<20).

Intervention

Potassium aspartate (2 vials K-Flebo d-1 = 60 mEq d-1, per os) for 4 weeks

Comparator

No potassium supplementation

Outcome

QT dispersion and QTc dispersion at 4 weekssurrogate
