Embarrassed Radiofrequency Catheter Ablation of Supraventricular Tachycardia in Pectus Excavatum

open access: yesThe Ewha Medical Journal, 2022
A 16-year-old patient with pectus excavatum visited our hospital because of palpitation. He underwent first Nuss operations at the age of 3. When he was 13 years old, the slow-fast type atrioventricular nodal reentrant tachycardia was documented during ...

High‐Density Electroanatomical Mapping of Alternating Short‐ and Long‐RP Orthodromic Tachycardia With Identical Atrial Breakthrough

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
High‐density electroanatomical mapping during orthodromic tachycardia with alternating short‐ and long‐VA conduction patterns demonstrated an identical earliest atrial breakthrough. Although this supports a common atrial insertion, it cannot distinguish functional longitudinal dissociation within a single accessory pathway from closely adjacent ...

Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

open access: yes, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia [PDF]

open access: yes, 2005
Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.

Electrocardiographic and Electrophysiologic Insights into Atrioventricular Nodal Re-entry Tachycardia: Diagnostic Update

open access: yesClinical Medicine Insights: Cardiology, 2012
Atrioventricular nodal re-entry tachycardia is a common supraventricular arrhythmia. The rate of recurrence is relatively high, and accordingly ablative therapy became the first-line suggested therapy.

Distinctive characteristics of His bundle potentials in patients with atrioventricular nodal reentrant tachycardia

open access: yesCardiology Journal, 2023
BACKGROUND: His bundle (HB) potentials vary in amplitude and duration in patients with and without slow pathways. The aim of this study was to determine the characteristics of HB potentials and to elucidate whether they can provide clues for ...

The sophisticated architecture of the rat atrioventricular node [PDF]

open access: yes, 2005
In the mammalian heart, the action potential spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node.

Zero Fluoroscopy Radiofrequency Slow‐Pathway Modification for AVNRT in Patients ≤ 21 Years: A Single‐Center Cohort and Contextual Review of Literature

open access: yesJournal of Arrhythmia, Volume 42, Issue 3, June 2026.
In 125 consecutive pediatric and young adult patients (age ≤ 21 years), zero‐fluoroscopy radiofrequency slow‐pathway modification for AVNRT—guided entirely by CARTO 3D electroanatomic mapping—achieved 100% acute success, zero recurrences at 36‐month follow‐up, and zero major complications, supporting fluoroless RF ablation as a durable first‐line ...

Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations [PDF]

open access: yes, 2005
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation.

Improvement in left ventricular deformational indices following radiofrequency ablation in patients with tachycardia: A comparative study between AVRT and AVNRT regarding left ventricular strain and strain rates

open access: yesResearch in Cardiovascular Medicine, 2016
Background: Ablation will efficiently lead to sinus rhythm preservation, which consequently improves left ventricular function; however, the strain rate and its indices as functional systolic factors of the left ventricle have not been studied ...
