Advances in modeling and characterization of atrial arrhythmias

Rieta, J J; Ravelli, Flavia; Sornmo, Leif (2013-12-05)

Atrial arrhythmias (AA) represent a common health problem in adults and may appear as a consequence of cardiac interventions as well as without any associated cardiac disease. In this respect, atrial fibrillation (AF) is ...
Detection of Dominant Reentries in Multichannel Electrograms of Atrial Fibrillation

Vraka, Aikaterini; Osorio, Diego; Bertomeu-González, Vicente; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2019-11-23)

[EN] Algorithms developed so far for the detection of local activation waves (LAWs) in electrograms (EGMs) of atrial fibrillation (AF) analyze each channel of the catheter separately, while dominant reentries of AF are ...
Linear and Nonlinear Correlations Between Surface and Invasive Atrial Activation Features in Catheter Ablation of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Bertomeu-González, Vicente; Hornero, Fernando; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (2021-09-15)

[EN] P-waves are vastly used to assess the outcome of catheter ablation (CA) of atrial fibrillation (AF). It remains unknown, however, if coronary sinus (CS), the key reference structure in CA procedures, follows similar ...
Novel Photoplethysmographic and Electrocardiographic Features for Enhanced Detection of Hypertensive Individuals

Cano, Jesús; Quesada, Aurelio; Ravelli, Flavia; Zangróniz, Roberto; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] Hypertension is a major risk factor for many cardiovascular diseases, which are the leading cause of death worldwide. Regular monitoring is essential to provide early diagnosis since most patients with elevated blood ...
Parallel Study on Surface and Invasive Recordings Across Catheter Ablation Steps of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Hornero, Fernando; Quesada, Aurelio; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] Catheter ablation (CA) is the star treatment of atrial fibrillation (AF). However, important issues regarding its procedure have only been superficially explored. While universal CA effect is assessed, the role of ...
Study on How Catheter Ablation Affects Atrial Structures in Patients with Paroxysmal Atrial Fibrillation: The Case of the Coronary Sinus

Vraka, Aikaterini; Bertomeu-González, Vicente; Osca, Joaquín; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2020-10-30)

[EN] It has been shown that substrate modification due to catheter ablation (CA), the first-line treatment of paroxysmal atrial fibrillation (PAF), provokes alterations in P-wave features of the surface electrocardiogram. ...
