Two patients with symptomatic fast/slow pathway double responses were evaluated with electrophysiology studies. Chronic palpitations were resistant or worsened by medical therapy. No reentry tachycardias were induced. A nonreentrant paroxysmal supraventricular tachycardia was documented, Radiofrequency ablation of the slow pathway was safely and successfully performed. Patients remain asymptomatic for 16‐18 months. Ablation of the slow pathway for this substrate is a viable option.
