Sudden cardiac death can be the first symptom. Analysis of data of 45 patients aged ≤10 years who underwent electrophysiological evaluation for WPW was performed. Thirty-three patients presented with tachycardia and four with syncope; eight were asymptomatic. Atrial fibrillation was induced in six patients, and it degenerated to ventricular fibrillation (VF) in two (1 of these patients was asymptomatic and the other had syncope); accessory pathway effective refractory period was ≤180 ms in both. Ablation was performed in 30 patients; the success rate was 90% (27/30) and recurrence rate was 17% (5/30). Induction of VF in two patients suggests that the prognosis of WPW in early childhood is not without risk. All patients with WPW pattern should be assessed electrophysiologically and risk-stratified. Ablation in patients with risk factors can prevent sudden death. Anahtar Kelimeler : Wolff-Parkinson-White, atriyal fibrilasyon, ventriküler fibrilasyon, supraventriküler taşikardi.
