Cardiovascular findings in adolescent inpatients with anorexia nervosa.

Left ventricular function, resting electrocardiograms, and Holter recordings were systematically examined in 25 consecutively hospitalized, seriously ill, emaciated adolescents with anorexia nervosa. We failed to observe serious arrhythmias, abnormal prolongation of QT interval, conduction abnormalities, or depression in left ventricular systolic function.
