[EN] Objective: The electrocardiogram (ECG) is currently the most widely used recording to diagnose cardiac disorders, including the most common supraventricular arrhythmia, such as atrial fibrillation (AF). However, ...
The analysis of P-wave variability from the electrocardiogram (ECG) has been suggested as an early predictor of the onset of paroxysmal atrial fibrillation (PAP). Hence, a preventive treatment could be used to avoid the ...
Atrial fibrillation (AF) is the most common cardiac arrhythmia in clinical practice. One frequent and very effective alternative to revert AF back to a normal sinus rhythm (NSR) is external electrical cardioversion (ECV). ...

[ES] La fibrilación auricular humana (FA) es la arritmia sostenida más común y se puede terminar mediante la ablación de regiones localizadas. De esta manera, una vez estudiados los mecanismos para la formación de fibrilación ...
[EN] Objective: To identify preoperative parameters of anatomo-electrical atrial remodelling in order to identify the subgroup of patients more favourable to long-term sinus rhythm (SR) re-establishment after concomitant ...
Atrial fibrillation (AF) is the most common cardiac arrhythmia in clinical practice. Although its termination mechanisms are not still completely known, previous works have reported significant electrocardiographic differences ...
Background and Objectives: Atrial fibrillation (AF) is the most common sustained cardiac ar- rhythmia and a growing healthcare burden worldwide. It is often asymptomatic and may appear as episodes of very short duration; ...

Atrial fibrillation (AF) is the most common supraventricular arrhythmia in clinical practice, thus, being the subject of intensive research both in medicine and engineering. Wavelet Entropy (WE) is a measure of the disorder ...
The standard electrocardiogram (ECG) is the most common non-invasive way to study atrial fibrillation (AF). In this respect, previous works have shown that the surface lead V 1 reflects mainly the dominant atrial frequency ...
Atrial fibrillation patients can be classified into paroxysmal, persistent and permanent attending to the temporal pattern of this arrhythmia. The surface electrocardiogram hides this differentiation. A classification ...
BACKGROUND Atrial remodeling as a result of long-standing persistent atrial fibrillation (AF) induces substrate modifications that lead to different perpetuation mechanisms than in paroxysmal AF and a reduction in the ...

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 ...

La fibrilación auricular (FA) es una de las arritmias cardiacas más comunes, la cual afecta alrededor del 10% de la población de más de 70 años. En FA, los impulsos eléctricos auriculares generados por el nodo sinusal son ...
Atrial fibrillation (AF) is the most commonly clinically-encountered arrhythmia.
Catheter ablation of AF is mainly based on trigger elimination and modification of the AF
substrate. Substrate mapping ablation of complex ...

The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method ...
Julián, M.; Alcaraz, R.; Rieta, J J(Elsevier, 2014-05-01)
Atrial fibrillation (AF) is today the most common sustained arrhythmia, its treatment being not completely satisfactory. Electrical activity organization analysis within the atria could play a key role in the improvement ...
Ibáñez Català, Xavier(Universitat Politècnica de València, 2016-03-11)
[EN] Atrial fibrillation (AF) is the most common sustained arrhythmia, increasing its prevalence with the age of the patients. The symptoms of AF considerably reduce the quality of life. However, the most important cause ...
