Orthodromic Atrioventricular Reentry Bradycardia and Tachycardia Caused by an Accessory Pathway in Horses. [PDF]

J Vet Intern Med
ABSTRACT Background Accessory pathways (APs) are muscular bundles directly connecting the atria and ventricles, bypassing the atrioventricular (AV) node‐His‐Purkinje system. Anterograde conduction along the AP results in ventricular preexcitation. A retrograde conducting AP allows ventriculo‐atrial (VA) conduction, creating a reentry circuit that ...

A Case of Junctional Ectopic Tachycardia and Complete Atrioventricular Block After Transcatheter Aortic Valve Replacement. [PDF]

Ann Noninvasive Electrocardiol
This case highlights junctional ectopic tachycardia (JET) and complete atrioventricular (AV) block after transcatheter aortic valve replacement (TAVR). JET after TAVR may be associated with AV block, potentially requiring rate control with medication and pacemaker implantation.

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

Extra-cardiac vagal stimulation: Clinical utility of a novel diagnostic and therapeutic tool in supraventricular tachycardia. [PDF]

J Arrhythm
Extracardiac vagal stimulation (ECVS) is a novel, safe tool inducing controlled AV/VA block. It assists SVT differential diagnosis, pathway unmasking, and ablation endpoint confirmation, adding value to EP procedures for supraventricular tachycardias.

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.

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.
