BACKGROUND Atrioventricular (AV) nodal reentrant tachycardia is classically described as
a reentrant rhythm entirely contained within the compact AV node. Although the concepts of …

A method using cryosurgery has been previously described to selectively ablate
atrioventricular nodal reentry tachycardia while preserving intact atrioventricular conduction …

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 …

Background Selective ablation of either the fast or the slow pathway resulting in cure of AV
nodal reentry tachycardia (AVNRT) has led to the concept that these pathways are discrete …

BACKGROUND The site of the reentrant circuit in atrioventricular (AV) junctional reentrant
tachycardia has not been defined; in particular, the existence of a common pathway of AV …

Pathology of Slow Pathway Ablation. Introduction: AV nodal reentrant tachycardia is
routinely cured using radiofrequency catheter ablation techniques. However, there remains …

AV Nodal Reentry. The classical model of “atrioventricular (AV) nodal” reentrant tachycardia
suggests that the reentrant circuit is entirely within the compact AV node and that AVnodal …

Background—The exact boundaries of the reentry circuit in atrioventricular nodal reentrant
tachycardia (AVNRT) have not been convincingly defined. Methods and Results—To define …

BACKGROUND The circuit of atrioventricular (AV) nodal reentrant tachycardia may include
perinodal atrial myocardium. Furthermore, in patients with dual AV nodal pathways, the atrial …

The inferior atrial extensions of the atrioventricular (AV) node have been related to the
anatomic substrate of the slow pathway, but their role in AV nodal reentrant tachycardia …
