Frequency of Syncope in Patients with Accessory Atrioventricular Connection

Background: Syncope in patients with Wolff-Parkinson-White (WPW) syndrome is related to rapid reciprocating tachycardia or rapid ventricular response over the accessory pathway during atrial fibrillation (AF). The aim of this retrospective study is to evaluate the frequency of syncope in patients with WPW syndrome. Methods: We reviewed the records of 150 consecutive patients with WPW syndrome.Results: There were 20 patients (13.3%) who reported at least one episode of syncope and 130 patients (86.7%) without such a history.Conclusion: Syncope is relatively frequent in patients with WPW. Patient with WPW syndrome who has experienced this symptom should be thoroughly evaluated.
