[EN] Although the surface electroenterogram (EEnG) is a weak signal contaminated by strong physiological interference, such as ECG and respiration, abdominal surface recordings of the EEnG could provide a non-invasive ...
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 ...

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 ...
Atrial fibrillation, which is the most common
cardiac arrhythmia, is typically classified into four clinical
subtypes: paroxysmal, persistent, long-standing persistent
and permanent. The ability to distinguish between
them ...
Objective: There is an ongoing research effort devoted to characterize the signal regularity metrics approximate entropy (ApEn) and sample entropy (SampEn) in order to better interpret their results in the context of ...

[ES] Varios grupos de investigación han propuesto distintos protocolos de registro electrocardiográfico de superficie no estándar para cuantificar de manera específica señales de Fibrilación Auricular (FA). Por lo tanto, ...
[EN] Surface Laplacian estimates via concentric ring electrodes (CREs) have proven to enhance spatial resolution compared to conventional disc electrodes, which is of great importance for P-wave analysis. In this study, ...
Introduction. Artifactual variations in the ST segment may lead to confusion with acute coronary syndromes. Objective. To evaluate
how the technical characteristics of the recording mode may distort the ST segment. Material ...
