A 14-year-old girl with anorexia nervosa was admitted to our hospital because of severe weight loss. She was 152 cm in height and weighed 27 kg. An echocardiogram demonstrated normal left ventricular contraction and a small left ventricular end-diastolic dimension. Pulsed Doppler transmitral flow demonstrated normal early filling velocities but a complete absence of late diastolic flow after the apparent electrocardiographic P wave, consistent with atrial electromechanical dissociation, so called atrial failure. Six months after admission, her body weight increased to 42 kg. Pulsed Doppler showed a normal transmitral flow pattern in both early and late diastole. We do speculate that atrial failure was related to malnutrition due to anorexia nervosa. Atrial failure can be one of the clinical features of patients with anorexia nervosa.
一名14岁神经性厌食症女孩因严重体重减轻入住我院。她身高152厘米，体重27千克。超声心动图显示左心室收缩正常，左心室舒张末期内径较小。脉冲多普勒二尖瓣血流显示早期充盈速度正常，但在明显的心电图P波后舒张末期血流完全缺失，符合心房电机械分离，即所谓的心房衰竭。入院6个月后，她的体重增加到42千克。脉冲多普勒显示舒张早期和晚期二尖瓣血流模式均正常。我们确实推测心房衰竭与神经性厌食症导致的营养不良有关。心房衰竭可能是神经性厌食症患者的临床特征之一。
