Electrocardiographic Predictors of Cardiac Reverse Remodeling After Left Bundle Branch Area Pacing in Atrioventricular Block: Emphasis on Post‐Pacing QRS Duration

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
In patients with atrioventricular block undergoing left bundle branch area pacing, shorter post‐pacing QRS duration was associated with cardiac reverse remodeling. Post‐pacing QRS duration may represent a simple and clinically applicable electrocardiographic marker for identifying patients more likely to achieve reverse remodeling.

Data_Sheet_1_Predictive Value of Tpeak – Tend Indices for Adverse Outcomes in Acquired QT Prolongation: A Meta-Analysis.PDF

, 2018
Background: Acquired QT interval prolongation has been linked with malignant ventricular arrhythmias, such as torsade de pointes, in turn predisposing to sudden cardiac death. Increased dispersion of repolarization has been identified as a pro-arrhythmic

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, Volume 97, Issue 8, Page 4282-4292, August 2026.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, Volume 604, Issue 16, Page 6792-6816, 15 August 2026.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

Temporal Variability in Electrocardiographic Indices in Subjects With Brugada Patterns

Frontiers in Physiology, 2020
IntroductionPatients with Brugada electrocardiographic (ECG) patterns have differing levels of arrhythmic risk. We hypothesized that temporal variations in certain ECG markers may provide additional value for risk stratification.

Electrocardiographic markers of proarrhythmogenicity in metabolic syndrome [PDF]

Българска кардиология
The etiopathogenetic mechanisms of metabolic syndrome that affect cardiac electrophysiology and lead to myocardial remodelling are numerous. Cardiomyocyte changes induced by metabolic and proinflammatory factors impair repolarization, exacerbate the ...

Sustainable Carbon Fiber Composites Based on Recyclable Bio‐Based Vanillin Thermoset Polymers

Polymer Composites, Volume 47, Issue 8, Page 7184-7195, 20 April 2026.
Development of composite materials made from a bio‐based and mechanically recycled vitrimeric polymer matrix. ABSTRACT Although bisphenol A (BPA) is the most used organic compound in the production of thermosets for composite materials, there has been an urgent scientific concern to eliminate it in the last years due to the environmental issues raised ...

Common Genetic Variants Modulate the Electrocardiographic Tpeak-to-Tend Interval [PDF]

, 2020
Sudden cardiac death is responsible for half of all deaths from cardiovascular disease. The analysis of the electrophysiological substrate for arrhythmias is crucial for optimal risk stratification.

Body Surface Mapping of Ventricular Repolarization Heterogeneity: An Ex-vivo Multiparameter Study

Frontiers in Physiology, 2020
BackgroundIncreased heterogeneity of ventricular repolarization is associated with life-threatening arrhythmia and sudden cardiac death (SCD). T-wave analysis through body surface potential mapping (BSPM) is a promising tool for risk stratification, but ...
