Internal Jugular Vein as an Alternative Access for Pacemaker Implantation: A Mostly Left IJ Case Series

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Leadless pacemakers traditionally rely on femoral venous access, which may be limited in patients with unfavorable IVC anatomy, prior interventions, or situations where preserving femoral access is preferred. Internal jugular (IJ) access offers an alternative route, but real‐world data on IJ implantation of single‐ and dual‐chamber ...

Complementary use of conduction system pacing techniques for the “pace and ablate” strategy in permanent atrial fibrillation - a case report

Romanian Journal of Cardiology
The feasibility of the conduction system pacing combined with atrioventricular node ablation was demonstrated in patients with atrial fibrillation in whom rate control can’t be achieved with medication and heart failure.

Ventricular Synchrony in Targeted Right Ventricular Septal Pacing: A Prospective Paired Comparison to Apical Placement

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background/Objectives Right ventricular (RV) apical pacing, the standard pacing approach, often induces ventricular dyssynchrony, potentially impairing cardiac function. This study aims to investigate whether targeted RV septal pacing, guided by functional electrophysiological feedback during implantation, reduces ventricular dyssynchrony ...

Does the atrioventricular node conduct? [PDF]

, 1989
It is difficult to be certain wh en the term "conduction" was first applied to the transfer of atrial activation to the ventricles .' In 1894, Engelmann used the word "Leitung", which can be translated as "connection" or as "conduction" .2 In 1906 ...

Atrioventricular node dysfunction and ion channel transcriptome in pulmonary hypertension [PDF]

, 2016
Background—Heart block is associated with pulmonary hypertension, and the aim of the study was to test the hypothesis that the heart block is the result of a change in the ion channel transcriptome of the atrioventricular (AV) node.

Orthodromic Atrioventricular Reentry Bradycardia and Tachycardia Caused by an Accessory Pathway in Horses

Journal of Veterinary Internal Medicine
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.

Diagnostic Accuracy of 12‐Lead ECG Algorithms for Accessory Pathway Localization in WPW: A Meta‐Analysis

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background In Wolff–Parkinson–White (WPW) syndrome, accurate localization of accessory pathways before catheter ablation can improve procedural planning and efficiency. Several 12‐lead electrocardiographic (ECG) algorithms have been proposed, but their diagnostic performance has not been consistently established.

High success rate of atrioventricular node ablation with radiofrequency energy [PDF]

, 1991
Radiofrequency current was introduced as an alternative energy source for transcatheter ablation of cardiac arrhythmias to avoid the complications associated with direct current shocks.

Initial experience with ablation of the innervation surrounding sinus and atrioventricular nodes to treat paroxysmal bradyarrhythmia

Chinese Medical Journal, 2020
. Background. The symptomatic bradyarrhythmia is Class I indication for pacing therapy which is not a radical cure. The present study aimed to assess the feasibility and to present the initial results of the restricted ablation of the parasympathetic ...

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.
