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 ...

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 ...

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

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 ...

The Prognostic Ability of ECG Findings in Predicting Cardiovascular Events: A Five‐Year Nested Case—Cohort Study in an Iranian Population (Shiraz Heart Study)

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Electrocardiographic (ECG) markers may provide incremental prognostic value for cardiovascular disease (CVD) events beyond traditional ASCVD risk scores. This study aimed to evaluate the association between baseline ECG parameters and the incidence of cardiovascular events over 5 years in a nested case‐control cohort ...

Optimizing the predictive validity of NIRS kinetic profiles to predict aerobic capacity from a resting skeletal muscle occlusion test

Experimental Physiology, Volume 111, Issue 3, Page 738-750, 1 March 2026.
Abstract Measuring and monitoring individual cardiorespiratory fitness through a valid and accessible non‐exhaustive surrogate is required. Techniques measuring haemodynamics have shown promise, and this study aimed to optimize the predictive validity of these approaches alongside developing predictive equations.
