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 ...

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.

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 ...

Role of the perinodal region in atrioventricular nodal reentry: Evidence in an isolated rabbit heart preparation [PDF]

open access: yes, 1983
To evaluate the role of perinodal tissue in the genesis of atrioventricular (AV) nodal reentry, echo beats were induced by programmed stimulation in nine superfused rabbit atrial-atrioventricular nodal preparations.

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 ...

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 ...

Being Taken Seriously: Patients' Experiences of Participation in Care for Supraventricular Tachycardia—A Phenomenological Study

open access: yesScandinavian Journal of Caring Sciences, Volume 40, Issue 2, June 2026.
ABSTRACT Aims and Objectives For patients with a recurring and elusive heart disorder, participation is challenging because of the need for care across the healthcare system. This paper describes how patients with supraventricular tachycardia (SVT) experience participation in their healthcare encounters.

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 ...

Possible Deslanoside‐Induced Left Posterior Fascicular Ventricular Tachycardia: A Case Report

open access: yesAnnals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
A 73‐year‐old man with paroxysmal AF and no structural heart disease who developed left posterior fascicular ventricular tachycardia (LPFVT) shortly after intravenous Deslanoside administration for rate control. Highlights: cardiac glycosides, though effective for rate control, may occasionally precipitate Purkinje‐related ventricular tachycardia ...

ST‐Segment Elevation Following Adenosine Administration for SVT: Diagnostic Challenge in Acute Cardiac Care

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ST segment elevation following adenosine administration in the inferior leads (II, III, aVF). ABSTRACT Adenosine, used to treat paroxysmal supraventricular tachycardia, commonly causes flushing, sweating, palpitations, and hypotension. Rarely, it may induce ST‐segment elevation with chest pain, suggesting transient myocardial ischemia or coronary ...
