[EN] BACKGROUND Dominant frequency (DF) and rotor mapping have been proposed as noninvasive techniques to guide localization of drivers maintaining atrial fibrillation (AF).
OBJECTIVE The purpose of this study was to ...
[EN] Background and objective: The prevalence of atrial fibrillation (AF) has tripled in the last 50 years due to population aging. High-frequency (DFdriver) activated atrial regions lead the activation of the rest of the ...
Burden of atrial fibrillation (AF) can be reduced by ablation of sources of electrical impulses driving AF but driver identification is still challenging. This study presents a new methodology based on causality analysis ...

[ES] Las enfermedades cardiovasculares son las causantes de la mayoría de las muertes que se producen en el mundo occidental, siendo las arritmias cardiacas una de las enfermedades más frecuentes dentro de este ámbito. La ...
[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 ...
[EN] Although standard 12-lead ECG is the primary
technique in cardiac diagnostic, detecting different
cardiac diseases using single or reduced number of leads
is still challenging. The purpose of our team, itaca-UPV,

[EN] Background:
It is difficult to noninvasively phenotype atrial fibrillation (AF) in a way that reflects clinical end points such as response to therapy. We set out to map electrical patterns of disorganization and ...
[EN] Introduction
Ablation of high dominant frequency (DF) sources in patients with atrial fibrillation (AF) is an effective treatment option for paroxysmal AF. The aim of this study was to evaluate the accuracy of noninvasive ...
