Radiofrequency ablation of the slow pathway safely and successfully eliminated symptoms in 2 patients with fast/slow pathway double responses, who remained asymptomatic at 16-18 months.

Does radiofrequency ablation of the slow pathway improve symptoms in patients with symptomatic fast/slow pathway double responses?
Radiofrequency ablation of the slow pathway is a viable and effective option for patients with symptomatic fast/slow pathway double responses.
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.
Sorbera et al. (Tue,) conducted a case report in Symptomatic fast/slow pathway double responses (n=2). Radiofrequency ablation of the slow pathway was evaluated on Symptom resolution. Radiofrequency ablation of the slow pathway safely and successfully eliminated symptoms in 2 patients with fast/slow pathway double responses, who remained asymptomatic at 16-18 months.
