JAS-GAN: Generative Adversarial Network Based Joint Atrium and Scar Segmentations on Unbalanced Atrial Targets [PDF]
arXiv, 2021 Automated and accurate segmentations of left atrium (LA) and atrial scars from late gadolinium-enhanced cardiac magnetic resonance (LGE CMR) images are in high demand for quantifying atrial scars. The previous quantification of atrial scars relies on a two-phase segmentation for LA and atrial scars due to their large volume difference (unbalanced ...

Рациональная фармакотерапия в кардиологии, 2019 The article is devoted to the description of all types of atrial tachyarrhythmias, including inappropriate sinus tachycardia, which, as a rule, is not paid enough attention in the domestic literature, sinoatrial node reentrant tachycardia, focal and ...

Atrial fibrillation and atrial flutter in athletes [PDF]
British Journal of Sports Medicine, 2012 Atrial fibrillation (AF) is the most common arrhythmia in clinical practice, with an estimated prevalence of 0.4% to 1% in the general population, increasing with age to 8% in those above 80 years. The recognised risk factors for developing AF include age, structural heart disease, hypertension, diabetes mellitus or hyperthyroidism.

Nationwide resource utilization of dizziness/vertigo presentations to the ED
Eye &ENT Research, EarlyView.Abstract Objective This study aims to assess overall rates of neuroimaging (computed tomography [CT] or magnetic resonance imaging [MRI]) and cerebrovascular accidents (CVAs) in patients presenting to the emergency department (ED) with primary diagnoses of dizziness/vertigo to determine if neuroimaging is overused in this population.

Atrial Fibrillation Detection Using RR-Intervals for Application in Photoplethysmographs [PDF]
arXiv, 2023 Atrial Fibrillation is a common form of irregular heart rhythm that can be very dangerous. Our primary goal is to analyze Atrial Fibrillation data within ECGs to develop a model based only on RR-Intervals, or the length between heart-beats, to create a real time classification model for Atrial Fibrillation to be implemented in common heart-rate ...

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York
ESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

A dynamical interpretation of flutter instability in a continuous medium [PDF]
Journal of the Mechanics and Physics of Solids 54, 2391-2417, 2006, 2010 Flutter instability in an infinite medium is a form of material instability corresponding to the occurrence of complex conjugate squares of the acceleration wave velocities. Although its occurrence is known to be possible in elastoplastic materials with nonassociative flow law and to correspond to some dynamically growing disturbance, its mechanical ...

Automatic Mode Switching in Atrial Fibrillation [PDF]
, 2005 Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

ESC Heart Failure, Volume 12, Issue 2, Page 832-838, April 2025.Abstract Aim Heart failure (HF) is a highly prevalent condition managed in both primary care (PC) and hospital care (HC)‐based settings. HF patients managed in these two settings may differ in their demography, comorbidities and outcomes, so we aimed to compare the patient management in PC and HC in the Västra Götaland Region (VGR) in Sweden.
