Recommendations
1 B-NR 1. Patients with AF with rapid anterograde conduction (pre-
excited AF), and hemodynamic instability should be treated
with electrical cardioversion.
1 B-NR 2. For patients with AF with rapid anterograde conduction
(pre-excited AF), catheter ablation of accessory pathways
(APs) is recommended.
1 C-LD 3. In patients with AF with rapid anterograde conduction (pre-
excited AF) and hemodynamic stability, pharmacological
cardioversion with intravenous ibutilide or intravenous
procainamide is recommended as an alternative to elective
cardioversion.
3: Harm B-NR 4. For patients with AF with anterograde accessory pathway
conduction (pre-excited AF), pharmacological agents
that block AV nodal conduction (verapamil, diltiazem,
amiodarone, digoxin, adenosine, or beta blockers)
are contraindicated due to risk of precipitating VF or
hemodynamic deterioration.
