The impact of clinical result acquisition and interpretation on task performance during a simulated pediatric cardiac arrest: a multicentre observational study.

CJEM 2022 May 19. Epub 2022 May 19.

Pediatrics, University of Toronto, Toronto, ON, Canada.

Purpose: The acquisition and interpretation of clinical results during resuscitations is common; however, this can delay critical clinical tasks, resulting in increased morbidity and mortality. This study aims to determine the impact of clinical result acquisition and interpretation by the team leader on critical task completion during simulated pediatric cardiac arrest before and after team training.

Methods: This is a secondary data analysis of video-recorded simulated resuscitation scenarios conducted during Teams4Kids (T4K) study (June 2011-January 2015); scenarios included cardiac arrest before and after team training. Read More

Pediatrics - Emergency Medicine, University of Washington School of Medicine, Seattle, USA.

Ventricular tachycardia in pediatric emergency department patients is a high-risk, low-frequency event well suited for education through simulation. This technical report describes a simulation-based curriculum for Pediatric Emergency Medicine fellows and senior residents involving the evaluation and management of a 10-year-old female presenting with palpitations who is ultimately diagnosed with Belhassen tachycardia. The curriculum highlights the features that differentiate Belhassen tachycardia (idiopathic left posterior fascicular ventricular tachycardia) from supraventricular or other tachycardias, building upon foundational pediatric resuscitation skills and Pediatric Advanced Life Support (PALS) algorithms for advanced learners.

Diabetic Ketoacidosis With Refractory Hypokalemia Leading to Cardiac Arrest.

Cureus 2022 Mar 24;14(3):e23439. Epub 2022 Mar 24.

Department of Pediatrics, Division of Critical Care, Indiana University School of Medicine, Indianapolis, USA.

Diabetic ketoacidosis (DKA) is known to cause total body potassium depletion, but during initial presentation, very few patients are hypokalemic, and even fewer patients experience clinical effects. As the correction of acidosis and insulin drive potassium intracellularly, measured serum potassium levels decrease and require repletion. This phenomenon is well described, and severe hypokalemia necessitates delaying insulin therapy. Read More

When Adenosine Does Not Work: Apparent and Real Adenosine-Resistant Tachycardia.

Pediatr Emerg Care 2022 May;38(5):235-240

Professor of Pediatrics and Pediatric Cardiologist and Electrophysiologist, BC Children's Hospital Heart Centre, Department of Pediatric Cardiology, University of British Columbia, Vancouver, British Columbia, Canada.

Abstract: Supraventricular tachycardia (SVT) is the most common arrhythmia in the pediatric population. Adenosine is widely accepted as the first-line pharmacological treatment for hemodynamically stable SVT, constituting a class I recommendation in the 2020 American Heart Association guidelines for pediatric life support (2020 American Heart Association Guidelines for cardiopulmonary resuscitation and emergency cardiovascular care). As most pediatric SVTs are dependent on the atrioventricular node (AVN) for their propagation, and adenosine acts primarily on the AVN, adenosine will frequently terminate the arrhythmia. Read More

Arrhythmia and impaired myocardial function in heritable thoracic aortic disease: An international retrospective cohort study.

Eur J Med Genet 2022 Apr 12;65(6):104503. Epub 2022 Apr 12.

Centre for Medical Genetics, Ghent University Hospital, Ghent, Belgium; VASCERN HTAD European Reference Centre, Belgium; Department of Pediatrics, Division of Pediatric Cardiology, Ghent University Hospital, Ghent, Belgium; Department of Cardiology, Ghent University Hospital, Ghent, Belgium. Electronic address:

Background: Heritable thoracic aortic diseases (HTAD), typically entailing aortic complications, can be caused by pathogenic variants or likely pathogenic variants (PV/LPVs) in several genes, including fibrillin1 (FBN1), Actin Alpha2 (ACTA2) and genes encoding components of the transforming growth factor (TGF)-β signaling pathway. In addition to aortic complications, non-aortic cardiac disease such as impaired myocardial function and/or arrhythmia have been increasingly reported, mainly in Marfan syndrome with underlying FBN1 PV/LPVs and are acknowledged as additional causes of morbidity and mortality. The prevalence of these manifestations in the various HTAD entities is largely unknown. Read More

Ripple mapping: A precise tool for atrioventricular nodal reentrant tachycardia ablation.

J Cardiovasc Electrophysiol 2022 Apr 13. Epub 2022 Apr 13.

Division of Pediatric Cardiology, Department of Pediatrics, Baylor College of Medicine, Texas Children's Hospital, Houston, Texas, USA.

Introduction: Ablation for atrioventricular nodal reentrant tachycardia (AVNRT) classically utilizes evaluation of signal morphology within the anatomic region of the slow pathway (SP), which involves subjectivity. Ripple mapping (RM; CARTO-3 Biosense Webster Inc) displays each electrogram at its three-dimensional coordinate as a bar changing in length according to its voltage-time relationship. This allows prolonged, low-amplitude signals to be displayed in their entirety, helping identify propagation in low-voltage areas. Read More

Tex Heart Inst J 2022 03;49(2)

The Heart Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio.

Patients with left ventricular noncompaction (LVNC) are at risk of clinically significant arrhythmias and sudden death. We evaluated whether implantable loop recorders could detect significant arrhythmias that might be missed in these patients during annual Holter monitoring. Selected pediatric and adult patients with LVNC who consented to implantable loop recorder placement were monitored for 3 years (study duration, 10 April 2014-9 December 2019). Read More
