Why the study?
Does slow pathway ablation combined with digitalis and beta-blockers increase ventricular cycle length during induced atrial fibrillation in patients with dual AV nodal pathways?
Does slow pathway ablation combined with digitalis and beta-blockers increase ventricular cycle length during induced atrial fibrillation in patients with dual AV nodal pathways?
Slow pathway ablation combined with digitalis and beta-blockers significantly decreases ventricular rate during atrial fibrillation with high sympathetic tone.

Supports adjunctive digitalis plus beta-blocker during isoproterenol to enhance post-ablation AF cycle length; confirms benefit in dual AV nodal pathways.
