We have studied 36 patients (19 females and 17 males), controlled between 1973 and 1989, who suffered Wolff-Parkinson-White (WPW) pattern in their electrocardiogram. Epidemiological, clinical, diagnostic, therapeutic and evolutional data were reviewed. The mean age at the time of diagnosis was 4 years and 3 months, with 48% younger than six months of age. The average time for the follow-up period was 4 years and 2 months. There was not familiar occurrence. Six (16%) of the patients had associated heart disease. Seventeen (47%) had type A of WPW, 12 (33%) type B and 7 (20%) were not defined. An echocardiographic study was done in 20 patients (61%). Twenty-seven patients (75%) showed supraventricular tachycardia (SVT), which in 22 of these cases was the reason for seeking consultation. Children without SVT, 9 (25%), did not need any form of treatment. Twenty-four (889) of the patients with SVT required treatment to prevent recurrence. In the 27 studied episodes of SVT, Verapamil IV (55%) and vagal manoeuvres were the most efficient treatments. Seventeen (47%) of the patients presented a persistent WPW pattern and 11 (31%) experienced a normalization of their electrocardiogram with a mean time of 2 years-2 months.
我们研究了36例患者（19例女性和17例男性），这些患者在1973年至1989年期间接受对照，其心电图呈现预激综合征（WPW）模式。回顾了流行病学、临床、诊断、治疗及病情演变数据。诊断时的平均年龄为4岁3个月，48%的患者年龄小于6个月。随访期的平均时间为4年2个月。无家族发病情况。6例（16%）患者伴有心脏病。17例（47%）为A型WPW，12例（33%）为B型，7例（20%）未明确分型。20例患者（61%）进行了超声心动图检查。27例患者（75%）出现室上性心动过速（SVT），其中22例因该症状前来就诊。无SVT的儿童有9例（25%），无需任何形式的治疗。24例（88%）有SVT的患者需要治疗以预防复发。在27次研究的SVT发作中，静脉注射维拉帕米（55%）和迷走神经手法是最有效的治疗方法。17例患者（47%）持续存在WPW模式，11例（31%）心电图恢复正常，平均时间为2年2个月。
