Transjugular Leadless Pacemaker Implantation in an Adolescent With Central Hypoventilation Syndrome: A Case Report

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Permanent pacing in pediatric patients is complicated by small body size, vascular access limitations, and the need for durable long‐term management. Leadless pacemakers offer an emerging alternative that minimizes infection and lead‐related complications, yet vascular access remains a key challenge in young patients.

Radiofrequency Catheter Ablation for Atrioventricular Node Reentry Tachycardia with Multiple Slow Atrioventricular Node Pathways.

open access: yesJapanese Circulation Journal, 1995
Catheter ablation was attempted in 2 patients with atrioventricular node reentry tachycardia which showed fast, intermediate and slow anterograde atrioventricular node pathways. Radiofrequency currents were applied within a restricted area of the tricuspid annulus between the His bundle and the ostium of the coronary sinus where presumed slow pathway ...

Frequency-dependent anti arrhythmic effects of crataegus monogyna on the extracellular field potential recordings in the rabbit atrioventricular node, an experimental model of AF [PDF]

open access: yes, 2011
Introduction: Despite extensive studies that have been performed on the effects of Crataegus monogyna in cardiovascular diseases, only few investigations have addressed the antiarrhythmic properties of this plant.

Exponential distribution of long heart beat intervals during atrial fibrillation and their relevance for white noise behaviour in power spectrum [PDF]

open access: yes, 2006
The statistical properties of heart beat intervals of 130 long-term surface electrocardiogram recordings during atrial fibrillation (AF) are investigated.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...

Surgical and Electrical Anatomy of the Inter-Nodal and Intra-Atrial Conduction System in the Heart

open access: yesJournal of Chest Surgery, 2022
An anatomical understanding of the atrial myocardium is crucial for surgeons and interventionists who treat atrial arrhythmias. We reviewed the anatomy of the inter-nodal and intra-atrial conduction systems.

Automatic Mode Switching in Atrial Fibrillation [PDF]

open access: yes, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Shortening of the Short Refractory Periods in Short QT Syndrome. [PDF]

open access: yes, 2017
BACKGROUND: Diagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown.

Atrial fibrillation, sinoatrial and atrioventricular node dysfunction in a mouse model of heart failure with preserved ejection fraction

open access: yesExperimental Physiology, EarlyView.
Summary of the timeline of characterized events related to atrial fibrilation (AF) and diastolic dysfunction in a mouse heart failure with preserved ejection fraction (HFpEF) model. Three weeks after the initiation of the diet regimen with high fat diet (HFD) and Nω‐nitro‐l‐arginine methyl ester (l‐NAME) in drinking water to induce HFpEF, significantly

Electrophysiological differences of randomized deep sedation with dexmedetomidine versus propofol

open access: yesBMC Anesthesiology
Background Dexmedetomidine and propofol are common sedatives in intensive care units and for interventional procedures. Both may compromise sinus node function and atrioventricular conduction.
