Malignant ventricular arrhythmias in patients with implantable cardioverter-defibrillators: electrical signals which are predictors of recurrence

CorSalud, 2017
Introduction: There is a growing number of patients with implantable cardioverter-defibrillators. Recurrences are frequent and electrical shocks are the main factor affecting the quality of life. Objective: To identify the electrocardiographic predictors

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 ...

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.

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 ...

The Moderating Effect of Physical Activity Between IQOS Smoking and Ventricular Repolarization Parameters in Lebanese University Students

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Cigarette smoking is a major modifiable risk factor for cardiovascular morbidity and sudden cardiac death, in part through abnormalities in ventricular repolarization. However, little data are available on other tobacco products and alternative tobacco use delivery devices, such as heated tobacco products, as well as the modifying ...

The effect of sertindole on QTD and TPTE

, 2010
Recent research suggests that other surrogate markers than QTc, including QTc dispersion and Tpeak-Tend, may better correlate with cardiac arrhythmia risk.

Autonomic nerve activity and the short term variability of Tpeak–Tend interval in dogs with pacing-induced heart failure

BackgroundIn congestive heart failure (CHF), autonomic nervous system (ANS) activity is known to modulate arrhythmic risk through its effects on myocardial repolarization. An increased interval between the peak and the end of T wave (Tpeak–Tend) has been
