Radio-frequency catheter ablation has replaced antiarrhythmic-drug therapy for the
treatment of many types of cardiac arrhythmia. This article reviews the biophysics and results …

BACKGROUND Atrioventricular (AV) nodal reentry is a relatively common cause of regular,
narrow QRS tachycardia. The underlying basis for this arrhythmia is functional (and …

Aims The anatomic substrates for atrioventricular nodal re-entry remain enigmatic, but
require knowledge of the normal arrangement of the inputs and exist from the …

Background Previous work has demonstrated that cells with AV nodal-type action potentials
are not confined to Koch's triangle but may extend along the AV orifices. The aim of this …

OBJECTIVES The purpose of this study was to determine the efficacy and risks of
radiofrequency ablation of various forms of supraventricular tachycardia after Mustard and …

Objectives. The purpose of this study was to prospectively compare in random fashion an
anatomic and an electrogram mapping approach for ablation of the slow pathway of …

Background Different subforms of AV nodal reentrant tachycardia (AVNRT) have been
described (“Slow/Fast”,“Slow/Slow” and “Fast/Slow”). Our aim is to improve definition of …

Objectives. The purpose off this prospective study was to test the hypothesis that the
elimination of inducible repetitive atrioventricular (AV) node reentry the persistence of slow …

Several models of the atrioventricular nodal reentrant tachycardia circuit have been
proposed. Recently, there has been experimental and clinical electrophysiology evidence …

Aims The exact circuit of atrioventricular nodal re-entrant tachycardia (AVNRT) remains
elusive. To assess the location and dimensions of the AVNRT circuit. Methods and results …
