A Three-Dimensional Model of the Human Atria With Heterogeneous Wall Thickness and Fibre Transmurallity - A Realistic Platform for the Study of Atrial Fibrillation

Rocher-Ventura, Sara; Martínez, Laura; López, Alejandro; Ferrer, Ana; Sánchez-Quintana, Damián; Saiz Rodríguez, Francisco Javier (IEEE, 2019-09-11)

[EN] Multiscale cardiac modelling has been increasingly used since it provides a promising framework to improve our understanding of atrial fibrillation physiopathology. In this study, we present a highly detailed ...
Atrial Fibrosis Hampers Non-invasive Localization of Atrial Ectopic Foci From Multi-Electrode Signals: A 3D Simulation Study

Godoy, Eduardo J.; Lozano, Miguel; García-Fernández, Ignacio; Ferrer-Albero, Ana; MacLeod, Rob; Saiz, Javier; Sebastián, Rafael (Frontiers Media SA, 2018-05-18)

[EN] Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be ...
Comparison between Hodgkin-Huxley and Markov formulations of cardiac ion channels

Carbonell Pascual, Beatriz; Godoy, Eduardo Jorge; Ferrer Albero, Ana; Romero Pérez, Lucia; Ferrero De Loma-Osorio, José María (Elsevier, 2016-06-21)

When simulating the macroscopic current flowing through cardiac ion channels, two mathematical formalisms can be adopted: the Hodgkin–Huxley model (HHM) formulation, which describes openings and closings of channel ...
Detailed Anatomical and Electrophysiological Models of Human Atria and Torso for the Simulation of Atrial Activation

Ferrer Albero, Ana; Sebastián Aguilar, Rafael; Sánchez Quintana, Damián; Rodriguez, José F.; Godoy, Eduardo Jorge; Martinez, Laura; Saiz Rodríguez, Francisco Javier (Public Library of Science, 2015-11-02)

Atrial arrhythmias, and specifically atrial fibrillation (AF), induce rapid and irregular activation patterns that appear on the torso surface as abnormal P-waves in electrocardiograms and body surface potential maps (BSPM). ...
Factors affecting basket catheter detection of real and phantom rotors in the atria: A computational study

Martínez-Mateu, Laura; Romero Pérez, Lucia; Ferrer Albero, Ana; Sebastián Aguilar, Rafael; Rodriguez Matas, José Félix; Jalife, José; Berenfeld, Omer; Saiz Rodríguez, Francisco Javier (Public Library of Science, 2018-03)

[EN] Anatomically based procedures to ablate atrial fibrillation (AF) are often successful in terminating paroxysmal AF. However, the ability to terminate persistent AF remains disappointing. New mechanistic approaches use ...
Human atria and torso 3D computational models for simulation of atrial arrhythmias

Sebastián Aguilar, Rafael; Ferrer Albero, Ana; Saiz Rodríguez, Francisco Javier (Universitat Politècnica de València, 2015-09-28)

Computational 3D models of human atria and torso with encoded anatomical and functional heterogeneity. The finite element model of the atria is a multi-layer mesh with a homogeneous wall thickness between 600 and 900 μm ...
Modelización 3D del torso humano para el estudio de arritmias auriculares. Procesamiento de mapas eléctricos superficiales

Ferrer Albero, Ana (Universitat Politècnica de València, 2013-03-21)

[ES] El desarrollo de modelos computacionales en el campo de la electrofisiología cardiaca ha permitido analizar in-silico el comportamiento auricular tanto a nivel celular y tisular como de órgano completo. Todos estos ...
Non-invasive localization of atrial ectopic beats by using simulated body surface P-wave integral maps

Ferrer Albero, Ana; Godoy, Eduardo Jorge; Lozano, Miguel; Martínez Mateu, Laura; Alonso Atienza, Felipe; Saiz Rodríguez, Francisco Javier; Sebastián Aguilar, Rafael (Public Library of Science, 2017-07-13)

Non-invasive localization of continuous atrial ectopic beats remains a cornerstone for the treatment of atrial arrhythmias. The lack of accurate tools to guide electrophysiologists leads to an increase in the recurrence ...
Three-dimensional Multiscale Modelling and Simulation of Atria and Torso Electrophysiology

Ferrer Albero, Ana (Universitat Politècnica de València, 2017-10-02)

A better understanding of the electrical activity of the heart under physiological and pathological conditions has always been key for clinicians and researchers. Over the last years, the information in the P-wave signals ...
Ventricular Tachycardia and Early Fibrillation in Patients With Brugada Syndrome and Ischemic Cardiomyopathy Show Predictable Frequency-Phase Properties on the Precordial ECG Consistent With the Respective Arrhythmogenic Substrate

Calvo, David; Atienza, Felipe; Saiz Rodríguez, Francisco Javier; Martinez, Laura; Ávila, Pablo; Rubín, José; Herreros, Benito; Arenal, Ángel; García-Fernández,Javier; Ferrer, Ana; Sebastian, Rafael; Martinez-Camblor, Pablo; Jalife, José; Berenfeld, Omer (Ovid Technologies Wolters Kluwer -American Heart Association, 2015-10)

[EN] Background¿ Ventricular fibrillation (VF) has been proposed to be maintained by localized high-frequency sources. We tested whether spectral-phase analysis of the precordial ECG enabled identification of periodic ...
