[Surgical treatment of tachycardia in children].

Based on the outcomes of surgical treatment in 127 children suffering from tachycardias, three clinical groups were identified: Group 1: an uncomplicated course; Group 2: tachycardias concurrent with congenital heart disease; Group 3: life-threatening tachyarrhythmias. The results of surgical treatment were the following by the groups: Group 1 showed its efficacy in 96.5% and a tachycardial relapse in 3.5%, Group 2 displayed it in 81.0%, deaths in 19.0%, Group 3 exhibited it in 93%, deaths in 7%. In the surgical treatment of the Wolff-Parkinson-White syndrome, the method of choice is epicardial fulguration of the accessory atrioventricular pathway (100% versus 89.4% for the W. Sealy procedure).
