[Radiofrequency ablation in the therapy of supraventricular and ventricular arrhythmias]

We summarize our experience with RF-ablation in 70 patients with symptomatic tachycardia (38 females and 32 males, age 25-73 years). 19 patients with AV reentry tachycardia in WPW-syndrome, 28 patients with node reentry tachycardia (AVNRT), 10 patients with ventricular tachycardia, 9 patients with atrial fibrillation and 4 patients with atrial flutter were treated. The primary success rate in the whole patient group is 87% and the longterm success rate (up to 1 year) 81%. RF-ablation of tachycardia is a highly effective therapy. The patients are free of symptoms and need no further medication. In patients with AVNRT in WPW-syndrome and ventricular tachycardia (structurally normal heart), RF-ablation is the therapy of choice. 32/70 patients were treated on an outpatient basis.
