[ES] Para contribuir a un abordaje optimizado de la ablacion por cateter (AC) de fibrilacion auricular (FA), durante los ultimos anos se han introducido complicados indices destinados a discriminar FA paroxistica de ...
Improved Discrimination Between Healthy and Hypertensive Individuals Combining Photoplethysmography and Electrocardiography

Cano, Jesús; Hornero, Fernando; Quesada, Aurelio; Martínez-Rodrigo, Arturo; Alcaraz, Raúl; Rieta, J J (2021-09-15)

[EN] Cardiovascular disease is one of the leading causes of death, with hypertension (HT) being its main risk factor. Its complications can be avoided with early treatment, but since these patients do not present any ...
Limb Versus Precordial ECG Leads as Improved Predictors of Electrical Cardioversion Outcome in Persistent Atrial Fibrillation

Cirugeda, Eva M.; Calero, Sofia; Quesada, Aurelio; Hidalgo, Victor M.; Rieta, J J; Alcaraz, Raul (IEEE, 2020-09-16)

[EN] Electrical cardioversion (ECV) is an effective and low-cost rhythm control strategy for persistent atrial fibrillation (AF). Because of its limited mid- and long-term success rates, prediction of early failure could ...
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 ...
Practical Considerations for the Application of Nonlinear Indices Characterizing the Atrial Substrate in Atrial Fibrillation

Finotti, Emanuela; Quesada, Aurelio; Ciaccio, Edward J.; Garan, Hasan; Hornero, Fernando; Alcaraz, Raúl; Rieta, J J (MDPI AG, 2022-09)

[EN] Atrial fibrillation (AF) is the most common cardiac arrhythmia, and in response to increasing clinical demand, a variety of signals and indices have been utilized for its analysis, which include complex fractionated ...
Predicción del fracaso temprano de la cardioversión eléctrica en fibrilación auricular sobre las 12 derivaciones del ECG estándar

Cirugeda Roldan, E.M.; Calero Núñez, S.; Quesada Dorador, A.; Hidalgo Olivares, V.M.; Rieta, J J; Alcaraz Martínez, R. (Sociedad Española de Ingeniería Biomédica, 2020-11-27)

[ES] Dentro de las tecnicas existentes para el control del ritmo cardiaco en fibrilacion auricular (FA), una de las mas extendidas es la cardioversion electrica (CVE). Esta tecnica, de aplicacion sencilla y bajo coste, ...
Refined Electrical Cardioversion Outcome Prediction with Bipolar Surface Standard Leads for Patients in Persistent Atrial Fibrillation

Cirugeda, Eva M.; Calero, Sofía; Quesada, Aurelio; Hidalgo, Víctor M.; Rieta, J J; Alcaraz, Raúl (IEEE, 2020-10-30)

[EN] For persistent atrial fibrillation (AF), a low-cost, simple and effective rhythm control strategy is electrical cardioversion (ECV). This procedure presents high mid- and long-term AF recurrence rates, so anticipation ...
