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

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 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.

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 ...

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.

Progressive increase of the Tpeak-Tend interval is associated with ischaemia-induced ventricular fibrillation in a porcine myocardial infarction model

, 2017
Aims:Repolarization indices of ECG have been widely assessed as predictors of ventricular arrhythmias. However, little is known of the dynamic changes of these parameters during continuous monitoring in acute ischaemic episodes.
