QT interval dispersion and resting metabolic rate in chronic anorexia nervosa.


OBJECTIVE During the starvation phase of anorexia nervosa (AN), cardiac and skeletal muscle mass decreases, whereas electrocardiographic QT dispersion, a marker of arrhythmia risk, increases. QT dispersion during the chronic phase of AN and its relationship to resting metabolic rate (RMR) have not been described previously and is the subject of the current… (More)
