Assessment of non-invasive time and frequency atrial fibrillation organization markers with unipolar atrial electrograms

Alcaraz, Raúl; Hornero, Fernando; Rieta, J J (IOP Publishing: Hybrid Open Access, 2011-01)

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 ...
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 ...
Novel Time-Frequency Features of the Fibrillatory Waves Improve Catheter Ablation Outcome Prediction of Persistent Atrial Fibrillation

Escribano, Pilar; Ródenas, Juan; Arias, Miguel A.; Langley, Philip; Rieta, J J; Alcaraz, Raúl (IEEE, 2020-10-30)

[EN] Despite its limited long-term success rate, catheter ablation (CA) is still the first-line treatment for patients suffering from persistent atrial fibrillation (AF). Preoperative prediction on the procedure¿s outcome ...
