PELLIZZON, Oscar A  and  NANNINI, Sebastián. Inducción de taquicardia reentrante nodal aurículo-ventricular por aplicación de radiofrecuencia. Medicina (B. Aires) [online]. 2017, vol.77, n.5, pp.433-436. ISSN 0025-7680.

Atrioventricular nodal reentrant tachycardia is the most common form of sustained regular narrow QRS complex tachycardia. It is caused by the presence of a dual atrioventricular nodal anatomy and physiology, with a fast and a slow pathway forming a substrate for re-entry. Electrophysiology study confirms the diagnosis when the tachycardia is induced, although in some cases this is not possible. Casuistry is here presented where the application of radiofrequency induced atrioventricular nodal reentrant tachycardia, when the electrophysiological study could not do it; we explain here its electrophysiological mechanism.

Keywords : Atrioventricular nodal reentrant tachycardia; Radiofrequency ablation; Induction by radiofrequency.
