[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 ...
Objectives: The aim of this paper was to study mechanisms of formation of fractionated electrograms on the posterior left atrial wall (PLAW) in human paroxysmal atrial fibrillation (AF). Background: The mechanisms responsible ...
[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 ...

[ES] La Fibrilación Auricular (FA) es la arritmia cardíaca más frecuente. Rápidamente se está convirtiendo en uno de los problemas de salud más significativos del mundo. A pesar de ser una enfermedad tan común, las estrategias ...
The present work introduces the first study on the P-wave morphological variability two hours preceding the onset of paroxysmal atrial fibrillation (PAF). The development of non-invasive methods able to track P-wave ...
[EN] Atrial fibrillation (AF) is nowadays the most common cardiac arrhythmia, being associated with an increase in cardiovascular mortality and morbidity. When AF lasts for more than seven days, it is classified as persistent ...

[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 ...
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 ...
Atrial fibrillation (AF) is the most common form of arrhythmia encountered in clinical practice. Its presence causes a rapid and irregular ventricular response, being the topic of intensive research in rate control therapies ...

[EN] Atrial fibrillation (AF) is a prevalent cardiac arrhythmia often treated concomitantly with other cardiac interventions through the Cox-Maze procedure. This highly invasive intervention is still linked to a long-term ...
[EN] Despite its limited long-term success rate, catheter
ablation (CA) is still the first-line treatment for patients suffering

[EN] Atrial fibrillation (AF) is the most spread
heart arrhythmia, whose mechanisms are not completely
clear yet. Catheter ablation is a standard treatment, which
isolates the area involved in the arrhythmia. Intracardia ...
BackgroundThe dominant atrial frequency is a key parameter for the analysis of atrial fibrillation (AF) from intracardiac recordings. The preprocessing approach employed by Botteron et al. in an early work is able to ...
[EN] Catheter ablation (CA) is the star treatment of atrial fibrillation (AF). However, important issues regarding its procedure have only been superficially explored. While universal CA effect is assessed, the role of ...
