2023 HRS/APHRS/LAHRS guideline on cardiac physiologic pacing for the avoidance and mitigation of heart failure

Journal of Arrhythmia, Volume 39, Issue 5, Page 681-756, October 2023., 2023
Abstract Cardiac physiologic pacing (CPP), encompassing cardiac resynchronization therapy (CRT) and conduction system pacing (CSP), has emerged as a pacing therapy strategy that may mitigate or prevent the development of heart failure (HF) in patients with ventricular dyssynchrony or pacing‐induced cardiomyopathy.

The spatial ventricular gradient is associated with adverse outcomes in acute pulmonary embolism

Annals of Noninvasive Electrocardiology, Volume 28, Issue 3, May 2023., 2023
The spatial ventricular gradient (SVG) is a vectorcardiographic measurement made on a standard 12‐lead electrocardiogram (ECG) that reflects cardiac loading conditions via electromechanical coupling. In this retrospective study of 317 patients presenting with acute pulmonary embolism (PE), patients with worse right ventricular (RV) function and more ...

Three‐dimensional electro‐anatomical mapping and radiofrequency ablation as a novel treatment for atrioventricular accessory pathway in a horse: A case report

Journal of Veterinary Internal Medicine, Volume 37, Issue 2, Page 728-734, March/April 2023., 2023
Abstract We describe the diagnosis and treatment of an atrioventricular accessory pathway (AP) in a horse using 3‐dimensional electro‐anatomical mapping (3D EAM) and radiofrequency catheter ablation (RFCA). During routine evaluation of the horse, intermittent ventricular pre‐excitation was identified on the ECG, characterized by a short PQ interval and

The diagnostic role of T wave morphology biomarkers in congenital and acquired long QT syndrome: A systematic review

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Numerous T wave morphology biomarkers, which can supplement QTc assessment in long QT syndrome (LQTS), have been identified. Their diagnostic capabilities include differentiation of genotypes, identification of concealed LQTS, differentiating acquired LQTS from congenital LQTS; and determining multichannel versus hERG channel blockade.

Steep repolarization time gradients in pig hearts cause distinct changes in composite electrocardiographic T‐wave parameters

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 ...

Accelerated QT adaptation following atropine‐induced heart rate increase in LQT1 patients versus healthy controls: A sign of disturbed hysteresis

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.

Synchronization of repolarization after cardiac resynchronization therapy: A combined clinical and modeling study

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.

Fragmented QRS is associated with ventricular arrhythmias in heart failure patients: A systematic review and meta‐analysis

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.

Identification of myocardial infarction using morphological features of electrocardiogram and vectorcardiogram

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

Annals of Noninvasive Electrocardiology, Volume 26, Issue 3, May 2021., 2021
Abstract Background The possible relationship between temporal variability of electrocardiographic spatial heterogeneity of repolarization and the risk of sudden cardiac death (SCD) in patients with coronary artery disease (CAD) is not completely understood.
