A robust wavelet-based approach for dominant frequency analysis of atrial fibrillation in body surface signals

Marques, V.G.; RODRIGO BORT, MIGUEL; Guillem Sánchez, María Salud; Salinet, J. (IOP Publishing, 2020-07)

[EN] Objective: Atrial dominant frequency (DF) maps undergoing atrial fibrillation (AF) presented good spatial correlation with those obtained with the non-invasive body surface potential mapping (BSPM). In this study, a ...
Body surface localization of left and right atrial high-frequency rotors in atrial fibrillation patients: A clinical-computational study

Rodrigo Bort, Miguel; Guillem Sánchez, María Salud; Climent, Andreu M.; Pedrón Torrecilla, Jorge; Liberos Mascarell, Alejandro; Millet Roig, José; Fernandez-Aviles, Francisco; Atienza, Felipe; Berenfeld, Omer (Elsevier, 2014-09)

Background: Ablation is an effective therapy in atrial fibrillation (AF) patients in which an electrical driver can be identified. Objective: The aim of this study is to present and discuss a novel and strictly non-invasive ...
Characterization of atrial arrhythmias in body surface potential mapping: A computational study

Gonçalves Marques, Victor; RODRIGO BORT, MIGUEL; Guillem Sánchez, María Salud; Salinet, Joao (Elsevier, 2020-12)

[EN] Purpose: Atrial tachycardia (AT), flutter (AFL) and fibrillation (AF) are very common cardiac arrhythmias and are driven by localized sources that can be ablation targets. Non-invasive body surface potential mapping ...
Mathematical modeling approaches for the diagnosis and treatment of reentrant atrial tachyarrhythmias

Liberos Mascarell, Alejandro (Universitat Politècnica de València, 2016-04-05)

[EN] Atrial tachyarrhythmias present a high prevalence in the developed world, and several studies predict that in the coming decades it will be increased. Micro or macro-reentrant mechanisms of the electrical wavefronts ...
Minimal configuration of body surface potential mapping for discrimination of left versus right dominant frequencies during atrial fibrillation

RODRIGO BORT, MIGUEL; Climent Martínez, Batiste Andreu; Liberos Mascarell, Alejandro; Fernández-Avilés, Francisco; Atienza, Felipe; Guillem Sánchez, María Salud; Berenfeld, Omer (Blackwell Publishing, 2017-08)

[EN] Background: Ablation of drivers maintaining atrial fibrillation (AF) has been demonstrated as an effective therapy. Drivers in the form of rapidly activated atrial regions can be noninvasively localized to either left ...
Noninvasive Localization of Maximal Frequency Sites of Atrial Fibrillation by Body Surface Potential Mapping

Guillem Sánchez, María Salud; Climent, Andreu M.; Millet Roig, José; Arenal, Ángel; Fernandez-Aviles, Francisco; Jalife, José; Atienza, Felipe; Berenfeld, Omer (American Heart Association, 2013-01)

Background—Ablation of high-frequency sources in patients with atrial fibrillation (AF) is an effective therapy to restore sinus rhythm. However, this strategy may be ineffective in patients without a significant dominant ...
Phase singularity point tracking for the identification of typical and atypical flutter patients: A clinical-computational study

Liberos Mascarell, Alejandro; RODRIGO BORT, MIGUEL; Hernández-Romero, Ismael; Quesada Dorador, Aurelio; Fernández-Avilés, Francisco; ATIENZA FERNANDEZ, FELIPE; Climent, Andreu M.; Guillem Sánchez, María Salud (Elsevier, 2019-01)

[EN] Atrial Flutter (AFL) termination by ablating the path responsible for the arrhythmia maintenance is an extended practice. However, the difficulty associated with the identification of the circuit in the case of atypical ...
Technical Considerations on Phase Mapping for Identification of Atrial Reentrant Activity in Direct- and Inverse-Computed Electrograms

RODRIGO BORT, MIGUEL; Martínez Climent, Andreu; Liberos Mascarell, Alejandro; Fernández-Avilés, Francisco; Berenfeld, Omer; Atienza, Felipe; Guillem Sánchez, María Salud (Ovid Technologies Wolters Kluwer -American Heart Association, 2017-09)

[EN] [Background] Phase mapping has become a broadly used technique to identify atrial reentrant circuits for ablative therapy guidance. This work studies the phase mapping process and how the signal nature and its filtering ...
