Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, EarlyView.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Morphological Substrates for Atrial Arrhythmogenesis in a Heart With Atrioventricular Septal Defect

Frontiers in Physiology, 2018
Due to advances in corrective surgery, congenital heart disease has an ever growing patient population. Atrial arrhythmias are frequently observed pre- and post-surgical correction. Pharmaceutical antiarrhythmic therapy is not always effective, therefore

Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

Effect of nitric oxide modulation on the basic and rate-dependent electrophysiological properties of AV-node in the isolated heart of rabbit: The role of adrenergic and cholinergic receptors [PDF]

, 2010
Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node.

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Possible Deslanoside‐Induced Left Posterior Fascicular Ventricular Tachycardia: A Case Report

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
A 73‐year‐old man with paroxysmal AF and no structural heart disease who developed left posterior fascicular ventricular tachycardia (LPFVT) shortly after intravenous Deslanoside administration for rate control. Highlights: cardiac glycosides, though effective for rate control, may occasionally precipitate Purkinje‐related ventricular tachycardia ...

Electrocardiography in horses, part 2: how to read the equine ECG [PDF]

, 2010
The equine practitioner is faced with a wide variety of dysrhythmias, of which some are physiological. The recording of an exercise electrocardiogram (ECG) can help distinguish between physiological and pathological dysrhythmias, underlining the ...

ST‐Segment Elevation Following Adenosine Administration for SVT: Diagnostic Challenge in Acute Cardiac Care

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ST segment elevation following adenosine administration in the inferior leads (II, III, aVF). ABSTRACT Adenosine, used to treat paroxysmal supraventricular tachycardia, commonly causes flushing, sweating, palpitations, and hypotension. Rarely, it may induce ST‐segment elevation with chest pain, suggesting transient myocardial ischemia or coronary ...
