Key result
Radiofrequency catheter ablation of the slow pathway reduced the mean ventricular rate during induced atrial fibrillation by at least 20% in the 3 patients who demonstrated dual AV nodal physiology.
Why the study?
Does radiofrequency catheter ablation of the slow pathway reduce the mean ventricular rate during induced atrial fibrillation in patients with drug-refractory paroxysmal atrial flutter or AVNRT?

Nakai et al. (1998) studied Paroxysmal atrial flutter or AVNRT with induced atrial fibrillation (n=6). Radiofrequency catheter ablation of the slow pathway vs. Pre-ablation baseline was evaluated on Reduction in mean ventricular rate during induced atrial fibrillation by ≥20%. Radiofrequency catheter ablation of the slow pathway reduced the mean ventricular rate during induced atrial fibrillation by at least 20% in the 3 patients who demonstrated dual AV nodal physiology.
