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 ...
Surface ECG organization time course analysis along onward episodes of paroxysmal atrial fibrillation

Alcaraz, Raul; Hornero, Fernando; Rieta, J J (Elsevier, 2011-07)

The complete understanding of the mechanisms leading to the initiation, maintenance and self-termination of atrial fibrillation (AF) still is an unsolved challenge for cardiac electrophysiology. Studies in which AF has ...
