Evaluation of QT dispersion and T-peak to T-end interval in patients with early-stage sarcoidosis

Revista Portuguesa de Cardiologia, 2017
Introduction and Aim: Sarcoidosis increases inhomogeneity in ventricular repolarization due to the presence of sarcoid granuloma, which significantly correlates with ventricular fibrillation. Various studies have suggested that the interval from the peak

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

The Journal of Physiology, EarlyView.
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 ...

Torsade de pointes induced by intravenous amiodarone therapy accompanied by marked augmentation of the transmural dispersion of repolarization in a patient with tachycardia‐induced‐cardiomyopathy

Annals of Noninvasive Electrocardiology, 2021
We report a 77‐year‐old human on renal dialysis for end‐stage renal disease with heart failure and atrial fibrillation (AF) complicated by a high ventricular frequency. The underlying disease was thought as tachycardia‐induced‐cardiomyopathy. Intravenous

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 ...

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.

Use of T-wave duration and Tpeak-Tend interval as new prognostic markers for patients treated with cardiac resynchronization therapy

, 2021
Background: The use of electrocardiography (ECG) is a practical method to evaluate the response to cardiac resynchronization therapy (CRT) implantation, as it is easily performed and saves time.Aim: This study aimed to assess the predictive value of the ...

Evaluation of Electrocardiographic T-peak to T-end Interval in Subjects with Increased Epicardial Fat Tissue Thickness

Arquivos Brasileiros de Cardiologia, 2015
Background:The association between periatrial adiposity and atrial arrhythmias has been shown in previous studies. However, there are not enough available data on the association between epicardial fat tissue (EFT) thickness and parameters of ventricular

LQT1 patients have augmented response of repolarization dispersion following atropine induced heart rate increase versus healthy controls

Physiological Reports, Volume 14, Issue 8, April 2026.
Abstract The long QT syndrome type 1 (LQT1) is caused by loss‐of‐function mutations affecting the potassium channel current IKs important for repolarization adaptation at heart rate (HR) increase. We therefore compared changes in three global VR dispersion parameters following a rapid, atropine‐induced HR increase in LQT1 patients versus healthy ...
