[Complete congenital atrioventricular block].

Revista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 2001
Congenital atrioventricular block is defined (Yater) as a documented conduction defect in a young subject with unquestionable bradycardia in the absence of a history of infection which might have caused the condition. This condition may be isolated or associated with structural cardiac disease.

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 ...

Fetal Heart Block and Endocardial Fibroelastosis With Subsequent Maternal Lupus Nephritis

Annals of Internal Medicine: Clinical Cases
Transplacental transfer of maternal anti-SSA/Ro antibodies may adversely impact fetal cardiac development in the second trimester. Antibody-mediated endocardial fibroelastosis (EFE) may develop with or without associated congenital block.

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 ...

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.

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
