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 ...

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

An Accessible Algorithm for the Quick and Precise Interpretation of Atrioventricular Blocks in Electrocardiograms

Annals of Noninvasive Electrocardiology, Volume 31, Issue 4, July 2026.
Interpretation of electrocardiograms (ECGs) using an algorithm can improve the detection and diagnosis of atrioventricular blocks in clinical practice. The proposed algorithm, with its high accuracy and structured approach, can help both experienced and less‐experienced healthcare professionals interpret ECGs with more precision, leading to early ...

Atrial Tachycardia Utilizing Bachmann's Bundle as an Epicardial Bypass: A Case Suggestive of a Dual‐Loop Mechanism

Annals of Noninvasive Electrocardiology, Volume 31, Issue 4, July 2026.
The activation propagated in a superior‐to‐inferior direction on the anterior wall and in an inferior‐to‐superior direction on the posterior wall (depicted with a yellow arrow). The activation jumped over the low voltage area on the anterior wall through the epicardial bridge (indicated by a white dotted arrow).

Causes of Persistent ST Elevation in Patients With Lung Cancer: A Case Report

Annals of Noninvasive Electrocardiology, Volume 31, Issue 4, July 2026.
ST elevation without Q waves in advanced cancer may suggest cardiac metastasis; voltage gradient while repolarization may cause ST elevation in cardiac metastasis. ABSTRACT Cardiac metastases are rare in clinical practice. Herein, we describe the case of a 61‐year‐old male patient who underwent radical left lung cancer surgery > 2 years before the ...

Stress native mapping does not distinguish patients with previous myocardial infarction with non‐obstructive coronary arteries from healthy volunteers

Clinical Physiology and Functional Imaging, Volume 46, Issue 4, July 2026.
Abstract Aims Patients with myocardial infarction with non‐obstructive coronary arteries (MINOCA) may be affected by coronary microvascular dysfunction with reduced stress perfusion. Changes in native T1 and T2 reflect changes in myocardial perfusion; therefore, the aim of our study was to investigate whether non‐contrast, adenosine stress native T1 ...

Choroid plexus remodeling linked to impaired CSF‐mediated clearance and Alzheimer's disease progression

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Impaired cerebrospinal fluid (CSF) ‐mediated clearance has been implicated in Alzheimer's disease (AD), but how choroid plexus (ChP) remodeling relates to these processes in vivo remains incompletely understood. METHODS In a large ADNI cohort, we integrated structural magnetic resonance imaging (MRI), amyloid/tau positron emission

The Heart of the Thymus: A Rare Tale of Nonischemic Cardiomyopathy in the Absence of Myasthenia Gravis

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Thymomas are rare epithelial tumors of the anterior mediastinum known for their association with autoimmune and paraneoplastic syndromes, most notably myasthenia gravis (MG). Cardiomyopathy is an exceptionally rare paraneoplastic manifestation.
