title: [Tachycardia-induced tachycardia: definitive treatment with radiofrequency ablation. Presentation of three cases].
abstract: Tachycardia-induced tachycardia is the phenomenon in which one tachycardia degenerates into another. Few data are available in patients suffering from AV nodal reentrant tachycardia an atrial fibrillation. For related to AV nodal reentrant triggered by tachycardia; there is a possible effective treatment by eliminating the slow nodal pathway, with radiofrequency ablation, as shown by other authors. In this study we present data on three patients with repeated episodes of documented atrial fibrillation and at least one episode of AV nodal reentrant tachycardia or regular palpitations. Radiofrequency ablation of the slow AV nodal pathway was successfully performed in both, and at a follow up of 6, 9 and 10 months, respectively, no new episode of AV nodal reentrant tachycardia or atrial fibrillation was documented.
