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

open access: yes, 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 ...

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

open access: yesAdvanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity

open access: yesAdvanced Science, EarlyView.
We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

Impact of atrial fibrillation on the cardiovascular system through a lumped-parameter approach [PDF]

open access: yes, 2014
Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering ...

Long‐Term Impact of Prosthesis‐Patient Mismatch After Transcatheter Aortic Valve Replacement in Patients With Small Aortic Annuli

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Prosthesis‐patient mismatch (PPM) remains common following transcatheter aortic valve replacement (TAVR) and is associated with worse clinical outcomes. PPM is of particular concern in small aortic annuli (SAA). Aims To compare the incidence, predictors, and long‐term impact of PPM in SAA TAVR.
