Computerized Modeling of Electrophysiology and Pathoelectrophysiology of the Atria -- How Much Detail is Needed? [PDF]

arXiv
This review focuses on the computerized modeling of the electrophysiology of the human atria, emphasizing the simulation of common arrhythmias such as atrial flutter (AFlut) and atrial fibrillation (AFib). Which components of the model are necessary to accurately model arrhythmogenic tissue modifications, including remodeling, cardiomyopathy, and ...

An efficient end-to-end computational framework for the generation of ECG calibrated volumetric models of human atrial electrophysiology [PDF]

arXiv
Computational models of atrial electrophysiology (EP) are increasingly utilized for applications such as the development of advanced mapping systems, personalized clinical therapy planning, and the generation of virtual cohorts and digital twins. These models have the potential to establish robust causal links between simulated in silico behaviors and ...

Segmenting Bi-Atrial Structures Using ResNext Based Framework [PDF]

arXiv
Atrial fibrillation (AF) is the most common cardiac arrhythmia, significantly contributing to mortality, particularly in older populations. While pulmonary vein isolation is a standard treatment, its effectiveness is limited in patients with persistent AF.

Atrial constitutive neural networks [PDF]

arXiv
This work presents a novel approach for characterizing the mechanical behavior of atrial tissue using constitutive neural networks. Based on experimental biaxial tensile test data of healthy human atria, we automatically discover the most appropriate constitutive material model, thereby overcoming the limitations of traditional, pre-defined models ...

Eletrograma Intramiocárdico na Avaliaçao da Estimulaçao Biventricular para Miocardiopatia Dilatada [PDF]

, 2001
Um paciente masculino de 64 anos de idade, com miocardiopatia dilatada, fibrilaçao atrial e bloqueio intraventricular, teve implantado um sistema de marcapasso (MP) composto de um gerador de dupla-câmara Physios CTM 01 e de dois eletrodos: um eletrodo ...
