本文报告1962～1980年St Louis儿童医院收治的3个月内心房扑动婴儿10例,其中男性9例。7例在出生时或生后不久发病,其余3例发生于生后第6、8和9周。出生体重为2,210～4,200g。出生时发病的7例中3例有心律失常症状,6周后发病的3例临床上均有充血性心力衰竭。多数患儿有不同程度的房室传导阻滞。有症状患儿的心室率比无症状者快(>250/分),房室传导阻滞则较轻。最初实验室检查结果(包括血常规、尿常规和血清电解质测定)均无异常。胸部X线检查显示心脏增大,心律转为正常窦性后心脏大小恢复正常。转为窦性心律后所作M型超声心动图检查亦正常。1例经心
This article reports 10 cases of atrial flutter in 3 months at St Louis Children’s Hospital from 1962 to 1980, including 9 males. Seven cases occurred at birth or shortly after birth, and the remaining three occurred at 6th, 8th and 9th weeks after birth. Birth weight of 2,210 ~ 4,200 g. Three of the seven patients who developed at birth had symptoms of arrhythmia. Three of the three patients who developed disease after 6 weeks had congestive heart failure clinically. Most children have varying degrees of atrioventricular block. Children with symptomatic ventricular rate than asymptomatic (> 250 / min), atrioventricular block was lighter. Initial laboratory test results (including blood tests, urine tests, and serum electrolytes) showed no abnormalities. Chest X-ray examination showed that the heart increased heart rate to normal sinus heart size returned to normal. M-mode echocardiography performed after conversion to sinus rhythm was also normal. 1 case of heart
