title: [Wolff-Parkinson-White disease in childhood: follow up of 36 cases].
abstract: 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.
