Answer

Cardiovascular complications account for most of the morbidity and mortality associated with anorexia nervosa. Electrocardiography (ECG) can reveal evidence of sinus bradycardia, ST-segment elevation, T-wave flattening, low voltage, and rightward QRS axis, although these changes are clinically insignificant. A finding of QT-interval prolongation, however, may indicate that the patient is at risk for cardiac arrhythmias and sudden death. [99, 75, 1]
