Supports ECG monitoring in anorexia nervosa despite normal-range QTc; extends evidence on progressive HR-BMI decoupling with disease duration.
Are heart rate and QTc interval altered in patients with anorexia nervosa compared to controls?
Patients with anorexia nervosa have significantly longer QTc intervals than controls, though still within normal limits, warranting careful cardiological surveillance.
Lesinskienė et al. (2008) studied this question.
