Annals of Noninvasive Electrocardiology, Volume 27, Issue 6, November 2022., 2022 In this article, we investigated the relation between (drug‐induced) repolarization time gradients (top) and T‐wave markers based on the 12‐lead ECG (bottom). We found that composite T‐wave markers, such as Tpeak–end, Twidth, and Tarea, show a good correlation with underlying RT heterogeneity, whereas standard clinical metrics such as QTtime do not ...

An evaluation of planarity of the spatial QRS loop by three dimensional vectorcardiography: its emergence and loss [PDF]
, 2017 Aims: To objectively characterize and mathematically justify the observation that vectorcardiographic QRS loops in normal individuals are more planar than those from patients with ST elevation myocardial infarction (STEMI).

Physiological Reports, Volume 10, Issue 21, November 2022., 2022 Accelerated QT adaptation after atropine in LQT1. During continuous Frank vectorcardiography, an intravenous bolus injection of atropine (0.04 mg*kg‐1 body weight) was used to induce a rapid heart rate increase in LQT1 patients and healthy controls with similar proportions of women and men.

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 8, Page 1837-1846, August 2022., 2022 Personalized in silico model showed that T‐wave area during CRT‐OFF is a sensitive marker for adaptations in ventricular repolarization after CRT. Abstract Introduction The changes in ventricular repolarization after cardiac resynchronization therapy (CRT) are poorly understood.

Annals of Noninvasive Electrocardiology, Volume 27, Issue 1, January 2022., 2022 Abstract Introduction Many primary prevention heart failure (HF) patients with an implantable cardiac defibrillator (ICD) rarely experience life‐threatening ventricular arrhythmias (VA). New strategies are required to identify patients most at risk of VA and sudden cardiac death who would benefit from an ICD.

IET Signal Processing, Volume 15, Issue 9, Page 674-685, December 2021., 2021 Abstract Cardiac failure, such as myocardial infarction (MI), is one of the most serious causes of mortality worldwide. MI is the sign of cardiac cell damage as a result of decreased blood oxygen level, which causes some morphological changes in the form of 12‐lead electrocardiogram (ECG) waves including T‐wave, Q‐wave, and ST‐segment. The main goal of
