Veterinary Record Case Reports, Volume 13, Issue 1, March 2025.Abstract Managing anaesthesia in dogs with sick sinus syndrome poses significant challenges due to bradyarrhythmias and life‐threatening hypotension. An 8‐year‐old, mixed‐breed dog with sick sinus syndrome underwent general anaesthesia for unilateral mastectomy.

Peri‐mortem arrhythmias in the non‐cardiac intensive care unit
Nursing in Critical Care, Volume 30, Issue 2, March 2025.Abstract Background Cardiovascular failure is recognized as a common final pathway at the end of life but there is a paucity of data describing terminal arrhythmias. Aim We aimed to describe arrhythmias recorded peri‐mortem in critically ill patients.

Reviving a failed network through microscopic interventions [PDF]
Nature Physics. 2022 Mar;18(3):338-49, 2020 From mass extinction to cell death, complex networked systems often exhibit abrupt dynamic transitions between desirable and undesirable states. Such transitions are often caused by topological perturbations, such as node or link removal, or decreasing link strengths.

Disorders of gut–brain interaction through the lens of polyvagal theory
Neurogastroenterology &Motility, Volume 37, Issue 3, March 2025.This paper introduces a metric, vagal efficiency (VE), that tracks a brainstem “switching” mechanism regulating blood pressure's effect on vagal control of the heart and gut. Potentially offering insights into gut–brain interaction disorders. Abstract This paper introduces a metric capable of tracking a hypothetical brainstem “switching” mechanism ...

Analysis of Heterogeneous Cardiac Pacemaker Tissue Models and Traveling Wave Dynamics [PDF]
arXiv, 2018 The sinoatrial-node (SAN) is a complex heterogeneous tissue that generates a stable rhythm in healthy hearts, yet a general mechanistic explanation for when and how this tissue remains stable is lacking. Although computational and theoretical analyses could elucidate these phenomena, such methods have rarely been used in realistic (large-dimensional ...

The Journal of Physiology, Volume 603, Issue 7, Page 1865-1885, 31 March 2025.Abstract figure legend Summary of strategies in modelling neurocardiac interactions using human pluripotent stem cells. Abstract Throughout our lifetime the heart executes cycles of contraction and relaxation to meet the body's ever‐changing metabolic needs. This vital function is continuously regulated by the autonomic nervous system.
