Familial Atrioventricular Nodal Reentry Tachycardia

PACE - Pacing and Clinical Electrophysiology, 2004
Dual atrioventricular nodal pathways, the substrate responsible for atrioventricular node reentry tachycardia (AVNRT), are thought to be randomly occurring congenital anomalies. This article describes 14 patients in six families, each with two or three first‐degree relatives with paroxysmal supraventricular tachycardia.

Atypical Atrioventricular Nodal Reentry Tachycardia with Atrioventricular Block Mimicking Atrial Tachycardia:

Journal of Cardiovascular Electrophysiology, 1997
AVNRT Mimicking Atrial Tachycardia, Introduction: Fast‐intermediate form AV nodal reentry tachycardia (AVNRT) sometimes may mimic atrial tachycardia or atrial flutter and render the diagnosis difficult when the tachycardia rate is fast and AV block occurs during tachycardia.

Inducible Atrioventricular Nodal Reentry Tachycardia in Infants with a History of Neonatal Orthodromic Reciprocating Tachycardia

PACE - Pacing and Clinical Electrophysiology, 2003
Atrioventricular nodal reentry tachycardia (AVNRT) is an uncommon mechanism of supraventricular tachycardia in neonates in whom orthodromic reciprocating tachycardia (ORT) predominates. We report three patients with structurally normal hearts who presented with neonatal ORT, documented by transesophageal electrophysiology studies at 2 to 3 weeks of ...

Induction of atrioventricular nodal reentry tachycardia with intravenous adenosine.

Singapore medical journal, 2007
Adenosine, used to terminate paroxysmal supraventricular tachycardia (SVT), is often useful in understanding the mechanism of tachycardia. This case report describes induction of SVT with adenosine in a 36-year-old man presenting with recurrent palpitations.

Anatomy for ablation of atrioventricular nodal reentry tachycardia and accessory pathways

Herzschrittmachertherapie + Elektrophysiologie, 2022
The atrioventricular (AV) valve plane and the central septum are of particular importance for electrophysiological diagnosis and interventional therapy of supraventricular tachycardias because accessory electrical connections of various types may be present in addition to the specific conduction system. Although modern 3D electroanatomic reconstruction

Atrial Tachycardia Mimicking Atrioventricular Nodal Reentry Tachycardia

The Journal of Emergency Medicine, 2013
The term supraventricular tachycardia (SVT) is used to describe tachydysrhythmias that require atrial or atrioventricular nodal tissue for their initiation and maintenance. SVT can be used to describe atrioventricular nodal reentry tachycardia, atrioventricular reentry tachycardia, and atrial tachycardia (AT).

Typical Atrioventricular Nodal Reentry Tachycardia

2020
A 21-year-old female underwent EP study for recurrent narrow-complex SVT. Several observations helped support the diagnosis. Typical AVNRT was diagnosed and the slow pathway was ablated with satisfactory results.

Atypical atrioventricular nodal reentry tachycardia in a child with polyvalvular dysplasia

Cardiology in the Young, 2014
AbstractA 10-year-old boy with polyvalvular dysplasia and severe involvement of both atrioventricular valves presented with palpitations. Concern was raised for atrial tachyarrhythmia due to biatrial enlargement; however, ambulatory monitoring discovered a reentrant mechanism.

Gender-Related Differences in Patients With Atrioventricular Nodal Reentry Tachycardia

The American Journal of Cardiology, 2006
The present study sought to assess the extent of gender differences in electrophysiologic parameters in patients with atrioventricular nodal reentrant tachycardia (AVNRT). The study population consisted of 203 patients (women/men ratio 2:1) who underwent slow pathway ablation.
