Discussion on pediatric exercise testing. Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults. QT prolongation and the occurrence of ventricular arrhythmias with exercise are another important aspect of exercise testing in children.

Shorten the Blanking Period After Atrial Fibrillation Ablation, Experts Say

DAIC

Cardiac Ablation in the Pediatric Population at a Tertiary Care Center in a Developing Country

Journal of Cardiovascular Electrophysiology

NOVEMBER 7, 2024

ABSTRACT Introduction The aim of this study was to describe our experience and outcome of ablation therapy for arrhythmias in pediatrics at a tertiary care center. All pediatrics presenting to AUBMC between 2000 and 2020 who underwent cardiac ablation were included. The completed procedures showed a success rate of 93%.

Abstract Introduction Supraventricular tachycardia (SVT) is a common pediatric arrhythmia. We describe the prescriptive tendencies, efficacy, and tolerability of BBs and CCBs used in the treatment of pediatric SVT. Methods and Results This is a multicenter retrospective cohort study from three academic children's hospitals.

Thromboembolic Complications From Atrial Fibrillation and Atrial Flutter in Pediatrics and Young Adults: A Multicenter Study

Journal of Cardiovascular Electrophysiology

DECEMBER 2, 2024

Objective To report the number of thromboembolic complications in a cohort of pediatric and young adult patients presenting with atrial fibrillation (AFib) or atrial flutter (AFl) while also assessing anticoagulation practice in a multicenter cohort of young patients with these arrhythmias.

This can be a source of cardiac arrhythmia as well. An important cause of arrhythmias in Ebstein’s anomaly is the presence of a right sided accessory atrioventricular pathway or WPW syndrome. Electrophysiological study will show that, and this pathway can be ablated. This portion is known as atrialized right ventricle.

In this pediatric study, it was 71% successful and better than amiodarone. Admission and referral to electrophysiology is always indicated. NOTE #3: In the context of a long QTc or ischemia — the finding of ST segment and/or T wave alternans may predict the occurrence of malignant ventricular arrhythmias.

OCTOBER 26, 2023

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. It is seldom done in pediatric age group. Opinion is divided on the need for electrophysiology study.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
