Lead‐Related and Procedural Outcomes of His Bundle Pacing Versus Left Bundle Branch Area Pacing in Patients Undergoing Atrioventricular Node Ablation: A Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
In patients undergoing atrioventricular node ablation, left bundle branch area pacing was associated with fewer chronic high‐threshold events, shorter procedural duration, and less atrioventricular nodal reconduction than His bundle pacing. Given the observational nature of available studies, these findings should be considered hypothesis‐generating ...

Evidence for Electrocardiographic Patterns Identifying Acute Coronary Occlusion in Non‐ST‐Elevation Acute Coronary Syndromes: A Scoping Review

Academic Emergency Medicine, Volume 33, Issue 8, August 2026.
ABSTRACT Background Approximately one‐quarter to one‐third of patients with non‐ST‐elevation myocardial infarction have a completely occluded culprit coronary artery but are not routinely referred for emergent reperfusion. A growing literature describes electrocardiographic patterns purported to identify acute coronary occlusion (ACO) in non‐STEMI ...

MAGNETO cardiography parameters to predict future Sudden Cardiac Death (MAGNETO-SCD) or ventricular events from implantable cardioverter defibrillators: study protocol, design and rationale

BMJ Open, 2020
Introduction Predicting sudden cardiac death (SCD) is challenging as current risk predictors have significant limitations. Evaluating magnetocardiogram (MCG) parameters could be of great value and we plan to assess the capability of a new mobile ...

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, Volume 183, Issue 15, Page 4321-4343, August 2026.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Association of Anti-Ro Antibodies with ECG Abnormalities in Systemic Lupus Erythematosus: A Cross-Sectional Study in a University Hospital

Novelty in Biomedicine
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with various cardiovascular manifestations. Anti-Ro antibodies are commonly found in SLE patients and may contribute to cardiac abnormalities, including electrocardiographic ...

Fragmented QRS on surface electrocardiogram as a predictor of perfusion defect in patients with suspected coronary artery disease undergoing myocardial perfusion imaging

Indian Heart Journal, 2018
Background: Fragmented QRS (FQRS) on surface electrocardiogram (ECG) is associated with the presence of myocardial scar tissue and may have prognostic value after certain ischemic events.

Pancreatic cancer cachexia promotes cardiac dysfunction through altered adrenergic signalling in the heart

The Journal of Physiology, Volume 604, Issue 15, Page 6281-6301, 1 August 2026.
Abstract figure legend The β1‐adrenergic receptor is the predominant adrenergic subtype expressed on cardiac myocytes. Upon stimulation it activates downstream signalling pathways that increase the heart rate and cardiac output to meet metabolic demands.

Early Repolarization, Fragmented QRS and Tpeak-Tend Interval as Electrocardiographic Markers in Patients with Idiopathic Ventricular Arrhythmias: a Brief Review

Journal of Cardiac Arrhythmias, 2020
Introduction: Idiopathic ventricular tachycardia and ventricular fibrillation, as causes of sudden cardiac death, are entities with mechanisms poorly studied and understood to date. The electrocardiogram (ECG) is a simple tool, but with great diagnostic

Simple ECG-based score and clinical parameters to predict right ventricular dilation in patients with repaired tetralogy of fallot

Open Heart
Background Cardiac magnetic resonance (CMR) is the gold standard for assessing right ventricular (RV) function in repaired tetralogy of Fallot (rTOF), but it is expensive and not always available. ECG is a cost-effective, accessible alternative.

Evaluation of QRS duration and presence of fragmented QRS in patients with inflammatory bowel disease

International Journal of Medical Sciences
Background: Inflammatory Bowel Disease (IBD) is mostly characterized by gastrointestinal tract involvement, however can also be accompanied with cardiac manifestations. QRS prolongation and the presence of QRS fragmentation (fQRS) have been previously evaluated in many chronic inflammatory diseases, as an independent predictor of cardiac events.
