Utilization and Prognosis of Cardiac Device Implantation in AL Versus ATTR Amyloidosis

Pacing and Clinical Electrophysiology, Volume 49, Issue 7, Page 954-961, July 2026.
ABSTRACT Introduction Cardiac amyloidosis can cause congestive heart failure, arrhythmias, and heart blocks, which frequently require cardiac device implantation (CDI). However, the differences between light chain (AL) amyloidosis and transthyretin (ATTR) amyloidosis CDI requirements are unknown. Methods A retrospective analysis was conducted using the

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

The Journal of Physiology, Volume 604, Issue 13, Page 5391-5420, 1 July 2026.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, Volume 604, Issue 13, Page 5378-5390, 1 July 2026.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Transient Sinus Node Dysfunction in a Postpartum Female with Sinus Bradycardia: A Case Report

Background: Conduction disorders are common cardiac complications during pregnancy in women with and without structural heart disease. Sinus bradycardia has been described in few case reports secondary to increased vagal tone.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, Volume 604, Issue 13, Page 5342-5354, 1 July 2026.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.
