Epilepsy–heart syndrome: Concept, clinical context, and opportunity for integrated care

Epilepsia, EarlyView.
Abstract In this concept paper, we introduce epilepsy‐heart syndrome as a shared burden of illness between epilepsy and cardiac disorders. This pragmatic definition is agnostic of which condition came first (the epilepsy or the cardiac disorder), recognising that these conditions can each serve as a risk factor for the other owing to a bidirectional ...

QR Sort: A Novel Non-Comparative Sorting Algorithm [PDF]

arXiv
In this paper, we introduce and prove QR Sort, a novel non-comparative integer sorting algorithm. This algorithm uses principles derived from the Quotient-Remainder Theorem and Counting Sort subroutines to sort input sequences stably. QR Sort exhibits the general time and space complexity $\mathcal{O}(n+d+\frac{m}{d})$, where $n$ denotes the input ...

Factors affecting the mean electrical axis of the heart in trained Thoroughbreds

Equine Veterinary Education, EarlyView.
Summary Background Assuming that the ventricular myocardium of horses is subjected to exercise‐induced hypertrophy, we hypothesised that the mean electrical axis (MEA) of the heart would change. Objectives To define a longitudinal study to detect any changes in the direction of the MEA in Thoroughbred horses using ECG.

Electrocardiograms from different types of exercise in Eventing horses with and without cardiac signs

Equine Veterinary Journal, EarlyView.
Abstract Background Exercising arrhythmias can be clinically irrelevant or associated with poor performance, collapse and sudden cardiac death. Objectives To test if readable exercising ECGs can be recorded by grooms or riders and to describe arrhythmias in ECGs from different types of exercise in Eventing horses and investigate associations with type ...
