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

Beginning of Ventricular Entrainment for Differentiation Between AVNRT and AVRT [PDF]

Zagazig University Medical Journal
Background: Differentiation between atrioventricular nodal reentry tachycardia (AVNRT) and accessory pathway-mediated atrioventricular reentrant tachycardia (AVRT) is challenging even during electrophysiological testing.Objective: To use the beginning of

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

Prevention of Atrioventricular Block During Radiofrequency Ablation by Pace Mapping of Koch’s Triangle [PDF]

Journal of Tehran University Heart Center, 2008
Background: Complete atrioventricular block (AV block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (AVNRT).

Interesting response to ventricular overdrive pacing during regular narrow QRS tachycardia. What is the mechanism?

Indian Pacing and Electrophysiology Journal, 2020
33 year old gentleman has undergone an electrophysiology study for recurrent paroxysmal palpitation. During one of the episodes of palpitation a regular narrow QRS tachycardia was documented which has terminated with intravenous adenosine.

ICD discrimination of SVT versus VT with 1:1 V-A conduction: A review of the literature

Indian Pacing and Electrophysiology Journal, 2015
Inappropriate ICD shocks are associated with increased mortality. They also impair patients' quality of life, increase hospitalizations, and raise health-care costs. Nearly 80% of inappropriate ICD shocks are caused by supraventricular tachycardia.

Ionic basis of a differential effect of adenosine on refractoriness in rabbit AV nodal and atrial isolated myocytes [PDF]

, 1999
Methods: The whole cell patch clamp technique was used to record action potentials and ion currents in AV nodal and left atrial myocytes isolated enzymatically from rabbit hearts.

Remote magnetic navigation shows superior long-term outcomes in pediatric atrioventricular (nodal) tachycardia ablation compared to manual radiofrequency and cryoablation

International Journal of Cardiology: Heart & Vasculature, 2021
Background: Catheter ablation (CA) is the first-choice treatment for tachyarrhythmia in children. Currently available CA techniques differ in mechanism of catheter navigation and energy sources.

Long-term outcomes after catheter-ablation of atrioventricular nodal reentrant tachycardia: A ten-year follow-up [PDF]

Vojnosanitetski Pregled, 2020
Background/Aim. Atrioventricular nodal (AV) reentry tachycardia (AVNRT) is the most common form of supraventricular tachycardia. Treatment of choice is a catheter-ablation of the slow pathway of the AV node.

Oral flecainide is effective in management of refractory tachycardia in infants

Indian Heart Journal, 2013
Background: Propranolol and digoxin have been used as first line drugs for treatment of supraventricular tachycardia (SVT) in infants. Flecainide and other drugs have been effective as a second line treatment for controlling refractory SVT.
