Changes in Atrioventricular Node Physiology Following Slow Pathway Modification in Patients with AV Nodal Re-entrant Tachycardia: The Hypothetical Suggestion of Mechanism of Noninducibility of AVNRT
Background and Objectives: In cases of radiofrequency catheter ablation (RFCA) for patients with atrioventricular nodal re-entrant tachycardia (AVNRT), complete elimination of slow pathway is not always achievable. Furthermore, in situations of the so-called modified slow pathway, the underlying mechanism of tachycardia elimination remains unclear. Subjects and Methods: Patients who underwent R...
متن کاملConduction properties of the antegrade fast and slow AV nodal pathways associated with AV nodal reentrant tachycardia.
To elucidate differences in conduction properties among the normal atrioventricular (AV) node and the antegrade fast and slow dual AV nodal pathways (DAVNPW), AV nodal conduction curves were analyzed quantitatively in 38 patients. Eighteen patients had antegrade DAVNPW with AV nodal reentrant tachycardia (AVNRT) (dual pathways group) and the remaining 20 had smooth AV nodal conduction curves, w...
متن کاملFast or slow pathway ablation (or neither) for AV nodal tachycardia?
Editorial Fast or slow pathway ablation (or neither) for AV nodal tachycardia? The recent rapid expansion of catheter ablation techniques for patients with atrioventricular nodal reentrant tachycardia (AVNRT) has been parallelled by a corresponding change in the threshold of referral for this treatment. Patients currently undergoing these procedures are often young and may not be severely sympt...
متن کاملAnatomic and functional characteristics of a slow posterior AV nodal pathway: role in dual-pathway physiology and reentry.
BACKGROUND The AV node is frequently the site of reentrant rhythms. These rhythms arise from a slow and a fast pathway for which the anatomic and functional substratum remain debated. This study proposes a new explanation for dual-pathway physiology in which the posterior nodal extension (PNE) provides the substratum for the slow pathway. METHODS AND RESULTS The anatomic and functional proper...
متن کاملTargeting the slow pathway for atrioventricular nodal reentrant tachycardia: initial results and long-term follow-up in 379 consecutive patients.
OBJECTIVES This study is designed to examine the immediate and short-term outcomes of patients who have undergone slow pathway ablation/modification for atrioventricular nodal reentrant tachycardia. BACKGROUND Targeting the slow pathway has emerged as the superior form of treatment for atrioventricular nodal reentrant tachycardia. This technique has been found effective and is associated with...
