[Corrected Q-T interval in the electrocardiogram in patients with anorexia nervosa]

This paper examined the corrected Q-T interval in a group of 15 patients with anorexia nervosa and in 30 patients of a control group. Prolonged corrected Q-T interval was found in 2 of 15 patients with anorexia nervosa (13%) and in one of 30 patients of a control group (3%). The correlation between corrected Q-T interval and body mass index in patients with anorexia nervosa was not found (r = +0.13). Relative risk for prolonged corrected Q-T interval in patients with anorexia nervosa was high (4.5) compared with a control group. It is well known that prolonged corrected Q-T interval is connected with a high risk for sudden death because of a malignant ventricular arrhythmias.
