"Moon River and Me": The film-song as leitmotiv in Breakfast at Tiffany's

Payri, Blas (Intellect, 2011-10)

This article analyses the efficiency of the leitmotiv derived from the song Moon River in Breakfast at Tiffany's. This leitmotiv is a musical element (the first three notes suffice to recognise Moon River) with the narrative ...
Alteration of the P-wave non-linear dynamics near the onset of paroxysmal atrial fibrillation

Martinez, Arturo; Abasolo, Daniel; Alcaraz, Raul; Rieta, J J (Elsevier, 2015-07)

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 ...

Application of Entropy-Based Features to Predict Defibrillation Outcome in Cardiac Arrest

Chicote, Beatriz; Irusta, Unai; Alcaraz, Raul; Rieta, J J; Aramendi, Elisabete; Isasi, Iraia; Alonso, Daniel; Ibarguren, Karlos (MDPI, 2016-09)

Prediction of defibrillation success is of vital importance to guide therapy and improve the survival of patients suffering out-of-hospital cardiac arrest (OHCA). Currently, the most efficient methods to predict shock ...
Application of Hurst exponents to assess atrial reverse remodeling in paroxysmal atrial fibrillation

Julián Seguí, Matilde; Alcaraz, Raul; Rieta, J J (IOP Publishing: Hybrid Open Access, 2015-11)

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 ...
Application of the relative wavelet energy to heart rate independent detection of atrial fibrillation

García, Manuel; Ródenas García, Juan; Alcaraz, Raúl; Rieta, J J (Elsevier, 2016-07)

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; ...
Central tendency measure and wavelet transform combined in the non-invasive analysis of atrial fibrillation recordings

Alcaraz, Raúl; Rieta Ibañez, José Joaquín (BioMed Central, 2012-08-09)

Background Atrial fibrillation (AF) is the most common supraventricular arrhythmia in the clinical practice, being the subject of intensive research. Methods The present work introduces two different Wavelet Transform ...
Classification of paroxysmal and persistent atrial fibrillation in ambulatory ECG recordings

Alcaraz, Raúl; Sandberg, Frida; Sornmo, Leif; Rieta Ibañez, José Joaquín (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)

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 ...
Comparative assessment of nonlinear metrics to quantify organization-related events in surface electrocardiograms of atrial fibrillation

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 ...
Electrocardiographic Spectral Features for Long-Term Outcome Prognosis of Atrial Fibrillation Catheter Ablation

Alcaraz, Raúl; Hornero, Fernando; Rieta, J J (Springer Verlag (Germany), 2016-11)

Atrial fibrillation (AF) is the most common arrhythmia in routine clinical practice. Despite many years of research, its mechanisms still are not well understood, thus reducing the effectiveness of AF treatments. Nowadays, ...
