Treatment of focal junctional tachycardia using ivabradine in a dog

Veterinary Record Case Reports, EarlyView.
Abstract A 10‐year‐old labrador retriever was referred as an emergency due to ascites and lethargy. Physical examination revealed a regular tachycardia at 160 beats per minute with a Grade 3/6, left apical systolic heart murmur. The dog was diagnosed with severe myxomatous mitral valve disease with biventricular congestive heart failure (mild pulmonary

Resolution of third‐degree atrioventricular block after antibiotic therapy in a dog (Canis lupus familiaris) with urinary tract infection

Veterinary Record Case Reports, EarlyView.
Abstract A 15‐year‐old, spayed, female Boxer dog presented to an emergency facility for collapsing episodes. Third‐degree atrioventricular block that was non‐responsive to atropine was diagnosed on electrocardiography. Initial diagnostics revealed a concurrent urinary tract infection and renal azotaemia.

Analysis of Arrhythmogenic Profile in a Canine Model of Chronic Atrioventricular Block by Comparing In Vitro Effects of the Class III Antiarrhythmic Drug Nifekalant on the Ventricular Action Potential Indices Between Normal Heart and Atrioventricular Block Heart

Journal of Pharmacological Sciences, 2007
The chronic atrioventricular block dog is a useful model for predicting the future onset of drug-induced long QT syndrome in clinical practice. To better understand the arrhythmogenic profile of this model, we recorded the action potentials of the ...

Constructing minimal blocking sets using field reduction [PDF]

J. Combin. Designs 24 (2015), 36-52, 2015
We present a construction for minimal blocking sets with respect to $(k-1)$-spaces in $\mathrm{PG}(n-1,q^t)$, the $(n-1)$-dimensional projective space over the finite field $\mathbb{F}_{q^t}$ of order $q^t$. The construction relies on the use of blocking cones in the {\em field reduced} representation of $\mathrm{PG}(n-1,q^t)$, extending the well-known

Artificial Cardiac Conduction System: Simulating Heart Function for Advanced Computational Problem Solving [PDF]

arXiv
This work proposes a novel bio-inspired metaheuristic called Artificial Cardiac Conduction System (ACCS) inspired by the human cardiac conduction system. The ACCS algorithm imitates the functional behaviour of the human heart that generates and sends signals to the heart muscle, initiating it to contract.

X chromosome aneuploidies and schizophrenia: association analysis and phenotypic characterization

Psychiatry and Clinical Neurosciences, Volume 76, Issue 12, Page 667-673, December 2022., 2022
Aim The aims of the present study were: (i) to examine the association between schizophrenia (SCZ) and 47, XXY or 47, XXX in a large case–control sample; and (ii) to characterize the clinical features of patients with SCZ with these X chromosome aneuploidies.

Serious outcomes among emergency department patients with presyncope: A systematic review

Academic Emergency Medicine, EarlyView.
Abstract Background Syncope is transient loss of consciousness, and in presyncope, patients experience same prodromal symptoms without losing consciousness. While studies have extensively reported the risk of serious outcome among emergency department (ED) syncope, the outcome for patients with presyncope and their management are not well studied.

Dual network structure of the AV node [PDF]

arXiv
Biological systems, particularly the brain, are frequently analyzed as networks, conveying mechanistic insights into their function and pathophysiology. This is the first study of a functional network of cardiac tissue. We use calcium imaging to obtain two functional networks in a subsidiary but essential pacemaker of the heart, the atrioventricular ...
