Mechanistic insights into sex differences in atrial electrophysiology and arrhythmia vulnerability through sex‐specific computational models

The Journal of Physiology, EarlyView.
Abstract figure legend Sex‐specific models of the human atrial myocyte in normal sinus rhythm (nSR) and chronic atrial fibrillation (cAF) revealed increased alternans susceptibility in cAF males and DADs in females, driven primarily by ICaL and ryanodine receptor remodelling.

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 ...

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.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1545-1559, March 2026.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

Prospective Respiratory Motion Correction Using Machine Learning and Pilot Tone (PROMPT) in Cardiac MRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1583-1595, March 2026.
ABSTRACT Purpose To implement and evaluate the feasibility of a Pilot Tone (PT)‐based prospective gating and tracking technique, which uses a long short‐term memory (LSTM) neural network to predict respiratory motion from PT signals. Methods A subject‐specific calibration scan consisting of 100 ECG‐triggered single‐shot images was performed ...
