RDF-star2Vec: RDF-star Graph Embeddings for Data Mining [PDF]

IEEE Access, Volume 11, pp.142030-142042, 2023, 2023
Knowledge Graphs (KGs) such as Resource Description Framework (RDF) data represent relationships between various entities through the structure of triples (). Knowledge graph embedding (KGE) is crucial in machine learning applications, specifically in node classification and link prediction tasks.

QT and Tpeak‐Tend interval variability: Predictive electrical markers of hospital stay length and mortality in acute decompensated heart failure. Preliminary data

Clinical Cardiology, Volume 45, Issue 12, Page 1192-1198, December 2022., 2022
Abstract Background As previously reported, an increased repolarization temporal imbalance induces a higher risk of total/cardiovascular mortality. Hypothesis The aim of this study was to assess if the electrocardiographic short period markers of repolarization temporal dispersion could be predictive of the hospital stay length and mortality in ...

Property (QT) for 3-manifold groups [PDF]

Algebr. Geom. Topol. 25 (2025) 107-159, 2021
According to Bestvina-Bromberg-Fujiwara, a finitely generated group is said to have property (QT) if it acts isometrically on a finite product of quasi-trees so that orbital maps are quasi-isometric embeddings. We prove that the fundamental group $\pi_1(M)$ of a compact, connected, orientable 3-manifold $M$ has property (QT) if and only if no summand ...

Recent heart rate history affects QT interval duration in atrial fibrillation. [PDF]

PLoS ONE, 2017
QT interval prolongation is associated with a risk of polymorphic ventricular tachycardia. QT interval shortens with increasing heart rate and correction for this effect is necessary for meaningful QT interval assessment.

Mexiletine Shortens the QT Interval in Patients With Potassium Channel-Mediated Type 2 Long QT Syndrome.

Circulation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Long QT syndrome is a potentially lethal yet highly treatable cardiac channelopathy. Although β-blocker therapy is standard for most patients, concomitant therapy with sodium channel blockers, like mexiletine, is often utilized for patients ...

Evaluation of Deutetrabenazine's Potential to Delay Cardiac Repolarization Using Concentration‐QTc Analysis

Clinical Pharmacology in Drug Development, Volume 12, Issue 1, Page 94-106, January 2023., 2023
Abstract Deutetrabenazine (Austedo) is indicated in adults for chorea associated with Huntington disease and tardive dyskinesia. Escalating deutetrabenazine doses were administered to healthy volunteers who were cytochrome P450 2D6 extensive/intermediate metabolizers (EMs) or poor metabolizers (PMs) to determine pharmacokinetic exposure of parent drug ...

Determination and Interpretation of the QT Interval: Comprehensive Analysis of a Large Cohort of Long QT Syndrome Patients and Controls

Circulation, 2018
Background: Long QT syndrome (LQTS) is associated with potentially fatal arrhythmias. Treatment is very effective, but its diagnosis may be challenging.

QT interval variability in body surface ECG: measurement, physiological basis, and clinical value: position statement and consensus guidance endorsed by the European Heart Rhythm Association jointly with the ESC Working Group on Cardiac Cellular Electrophysiology.

Europace, 2016
This consensus guideline discusses the electrocardiographic phenomenon of beat-to-beat QT interval variability (QTV) on surface electrocardiograms. The text covers measurement principles, physiological basis, and clinical value of QTV.
