Atrioventricular Ring Tachycardias: Atypical Fast-Slow Atrioventricular Nodal Reentrant Tachycardia and Atrial Tachycardia Share a Common Arrhythmogenic Substrate—A Unifying Proposal

چکیده
Our understanding of the variants slow pathway (SP) and associated atypical atrioventricular (AV) nodal reentrant tachycardia (NRT) is still growing. We have identified extending outside Koch’s triangle along tricuspid annulus, including superior, superoanterior inferolateral right atrial SP atypical, fast-slow AVNRT. review history each variant, their electrophysiological characteristics related AVNRT, treatment by catheter ablation. focused our efforts on organizing published information, as well some unpublished, reliable data, show pitfalls observations, with keys to diagnosis The superior-type AVNRT mimics adenosine-sensitive originating near AV node can be successfully treated ablation a superior form side perihisian region or from non-coronary sinus Valsalva. Fast-slow using also annulus. summarize similarities among these SP, origin tachycardias, anatomical distributions pharmacological characteristics. Moreover, based recent basic research reporting presence node-like ring tissue encircling annuli in adult hearts, we propose term “AV tachycardia” designate tachycardias that share common arrhythmogenic substrate. This should help readers recognize rare types diagnose cure complex tachycardias. hope, this proposal unified designation, open new chapter clinical electrophysiology.

Atypical Fast-Slow Atrioventricular Nodal Reentrant Tachycardia Incorporating a "Superior" Slow Pathway: A Distinct Supraventricular Tachyarrhythmia.
BACKGROUND The existence of an atypical fast-slow (F/S) atrioventricular nodal reentrant tachycardia (AVNRT) including a superior (sup) pathway with slow conductive properties and an atrial exit near the His bundle has not been confirmed. METHODS AND RESULTS We studied 6 women and 2 men (age, 74 ± 7 years) with sup-F/S-AVNRT who underwent successful radiofrequency ablation near the His bundle...

متن کاملCatheter Ablation of Atypical Atrioventricular Nodal Reentrant Tachycardia.
BACKGROUND Because of its low prevalence, data on atypical atrioventricular nodal reentrant tachycardia (AVNRT) are scarce, and the optimal ablation method has not been established. Our study aimed at assessing the efficacy and safety of conventional slow pathway ablation, as applied for typical cases, in atypical AVNRT. METHODS We studied 2079 patients with AVNRT subjected to slow pathway ab...
متن کاملRadiofrequency catheter ablation of atypical atrioventricular nodal reentrant tachycardia.
INTRODUCTION Published reports of radiofrequency ablation of atypical atrioventricular nodal reentrant tachycardia (AVNRT) have been limited. We present our experience in 10 consecutive patients with atypical AVNRT who underwent radiofrequency ablation of the "slow" AV nodal pathway. METHODS AND RESULTS There were 9 females and 1 male; their mean age was 44 +/- 19 years (+/- SD). The mean AVN...
