Autochthonous Babesia canis infections in 49 dogs in Germany
Journal of Veterinary Internal Medicine, Volume 37, Issue 1, Page 140-149, January/February 2023., 2023 Abstract Background Vector‐borne diseases are of increasing importance in Germany. Since 2015, autochthonous cases have been increasingly documented in Berlin/Brandenburg. Objectives Describe autochthonous Babesia canis infection in the Berlin/Brandenburg region. Animals Forty‐nine dogs with autochthonous B. canis infection.

A Computational Framework for Atrioventricular Valve Modeling using Open-Source Software [PDF]
arXiv, 2022 Atrioventricular valve regurgitation is a significant cause of morbidity and mortality in patients with acquired and congenital cardiac valve disease. Image-derived computational modeling of atrioventricular valves has advanced substantially over the last decade and holds particular promise to inform valve repair in small and heterogeneous populations ...

Model-based Estimation of AV-nodal Refractory Period and Conduction Delay Trends from ECG [PDF]
arXiv, 2023 Atrial fibrillation (AF) is the most common arrhythmia, associated with significant burdens to patients and the healthcare system. The atrioventricular (AV) node plays a vital role in regulating heart rate during AF, but is often insufficient in regards to maintaining a healthy heart rate.

A case of mesothelioma of the atrioventricular node [PDF]
Chinese Journal of Cancer Research, 1997 The case, a 8-year-old boy, who died from traffic accident. Grossly, the heart weights 115g and the inferior part of atrial septum is 3.6-4.0mm in thickness (1.8-2.0mm in thickness of this part in a normal heart). No other abnormalities were found in this heart.

Spread of Activity Through the Atrioventricular Node [PDF]
Circulation Research, 1960 Electrophysiologic mapping experiments on the excitation of the A-V node of isolated rabbit heart have been performed with intracellular microelectrodes. An area of tissue showing peculiar physiologic characteristics was shown to coincide, at least in part, with the histologic A-V node and His bundle.

Modeling isovolumetric phases in cardiac flows by an Augmented Resistive Immersed Implicit Surface Method [PDF]
arXiv, 2022 A major challenge in the computational fluid dynamics modeling of the heart function is the simulation of isovolumetric phases when the hemodynamics problem is driven by a prescribed boundary displacement. During such phases, both atrioventricular and semilunar valves are closed: consequently, the ventricular pressure may not be uniquely defined, and ...

Estimation of atrial fibrillation from lead-I ECGs: Comparison with cardiologists and machine learning model (CurAlive), a clinical validation study [PDF]
arXiv, 2021 Electrocardiogram recognition of cardiac arrhythmias is critical for cardiac abnormality diagnosis. Because of their strong prediction characteristics, artificial neural networks are the preferred method in medical diagnosis systems. This study presents a method to detect atrial fibrillation with lead-I ECGs using artificial intelligence.

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management
Advanced Science, EarlyView.Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

Animal Models and Experimental Medicine, EarlyView.Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss
