A Narrow QRS Tachycardia With Alternating R‐R Interval

Annals of Noninvasive Electrocardiology
We report a case of a 21‐year‐old female manifesting narrow QRS complex tachycardia and alternating R‐R intervals. The fixed RP interval suggested ventriculoatrial conduction via an accessory pathway (AP).

Zero Fluoroscopy Radiofrequency Slow-Pathway Modification for AVNRT in Patients ≤ 21 Years: A Single-Center Cohort and Contextual Review of Literature. [PDF]

J Arrhythm
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 ...

Simultaneous dual AV node antegrade conduction (2 for 1) and lower common pathway (2–1) block illustrate AVNRT physiology

Indian Pacing and Electrophysiology Journal, 2020
We report a rare case of spontaneous initiation of Atrioventricular nodal reentry tachycardia (AVNRT) via 2 for 1 phenomenon, into a 2:1 AV block due to lower common pathway block and finally transition to 1:1 tachycardia.

Prevalence and Structured Approach to the Diagnoses of A on V Tachycardias. [PDF]

J Arrhythm
Schematic tachycardia circuit diagram and corresponding laddergram depicting how atrial and ventricular activations become coincident to exhibit true A on V tachycardia, contrasted with the electrophysiologic basis of pseudo A on V patterns. ABSTRACT Background “A on V” tachycardia (AoV‐T) is classically considered suggestive of atrioventricular nodal ...

Long‐term follow‐up in preschool children after radiofrequency catheter ablation of arrhythmias

Journal of Arrhythmia, 2023
Background Radiofrequency ablation (RFA) is the standard method of treatment for tachyarrhythmias in school children, and it leads to complete recovery in children without structural heart disease. However, RFA in young children is limited by the risk of

The coexistence of Wolff-Parkinson-White syndrome (WPW) and atrioventricular nodal reentrant tachycardia (AVNRT)

Turkish Journal of Emergency Medicine, 2018
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of reentrant paroxysmal supraventricular tachycardia that occurs in the presence of dual AV nodal physiology.

Coronary sinus cannulation predicts atrioventricular nodal reentry as mechanism of supraventricular tachycardia

Indian Pacing and Electrophysiology Journal, 2019
Introduction: Common clinical teaching, for invasive electrophysiology, is that if the first year fellow cannulates the coronary sinus (CS) in his first attempt, the arrhythmia is more likely to be atrioventricular nodal reentry tachycardia (AVNRT). This

Atrioventricular nodal reentry tachycardia in pregnancy: ‘I have ice for you’

European Heart Journal - Case Reports, 2023
Abstract Background Pregnancy is a known trigger of novel and pre-existing supraventricular tachyarrhythmias. We present a case of a stable pregnant patient presenting with atrioventricular nodal reentry tachycardia (AVNRT) and application of the ‘facial ice immersion technique’.

Radiofrequency catheter ablation in infants and children

SA Heart Journal, 2017
Background: Diagnosis and treatment of paediatric arrhythmias remain challenging. Antiarrhythmic - drugs beta-blockers, class Ic and class III drugs, were the only treatment available for many years. Radiofrequency catheter ablation (RFCA) was introduced

Atrioventricular Nodal Re-entry Tachycardia in Identical Twins: A Case Report and Literature Review

Indian Pacing and Electrophysiology Journal, 2013
This report details the case of 17 year old identical twins who both presented with paroxysmal supraventricular tachycardia (PSVT). Electrophysiological studies revealed atrioventricular nodal reentry tachycardia (AVNRT) in both twins.
