Class I Guidelines
1. Catheter ablation of the accessory pathway is recommended in symptomatic patients with AF who have WPW syndrome, particularly those with syncope due to rapid heart rate or those with a short bypass tract refractory period. (Level of Evidence: B)

 ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class I Recommendation 1 for patients with Wolff Parkinson White syndrome (WPW) should be: CLASS I CLASS IIa CLASS IIb CLASS III 2. Immediate direct-current cardioversion is recommended to prevent ventricular fibrillation in patients with a short anterograde bypass tract refractory period in whom AF occurs with a rapid ventricular response associated with hemodynamic instability. (Level of Evidence: B)

 ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class I Recommendation 2 for patients with Wolff Parkinson White syndrome (WPW)should be: CLASS I CLASS IIa CLASS IIb CLASS III 3. Intravenous procainamide or ibutilide is recommended to restore sinus rhythm in patients with WPW syndrome in whom AF occurs without hemodynamic instability in association with a wide QRS complex on the ECG (greater than or equal to 120-ms duration) or with a rapid pre-excited ventricular response. (Level of Evidence: C)

 ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class I Recommendation 3 for patients with Wolff Parkinson White syndrome (WPW) should be: CLASS I CLASS IIa CLASS IIb CLASS III
