Cite This Study

Sorbera et al. (1999) 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.
