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 ...
Alternative Time-Domain P-wave Analysis for Precise Information on Substrate Alteration After Pulmonary Vein Isolation for Atrial Fibrillation

Vraka, Aikaterini; Bertomeu-González, Vicente; Hornero, Fernando; Sörnmo, Leif; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] While P-wave duration (PWD) is primarily employed to observe the atrial substrate alterations after pulmonary vein isolation (PVI) on atrial fibrillation (AF) patients, the acquired information corresponds to the ...
Desarrollo de un método robusto de delineación de onda P para registros electrocardiograficos basado en el modelo Gaussian. Evaluación sobre bases de datos estándar y personalizadas

González Molina, Francisco (Universitat Politècnica de València, 2020-07-01)

[EN] Atrial Fibrillation is the most common sustained cardiac arrhythmia. Its prevalence is even expected to increase in the coming years. Indeed, it is already considered an epidemic disease. However, the degenerative ...
Gaussian modeling of the P-wave morphology time course applied to anticipate paroxysmal atrial fibrillation

Martínez, Arturo; Alcaraz, Raúl; Rieta, J J (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2015-12-10)

This paper introduces a new algorithm to quantify the P-wave morphology time course with the aim of anticipating as much as possible the onset of paroxysmal atrial fibrillation (PAF). The method is based on modeling each ...
Morphological variability of the P-wave for premature envision of paroxysmal atrial fibrillation events

Martínez, Arturo; Alcaraz, Raul; Rieta, J J (IOP Publishing: Hybrid Open Access, 2014-01)

The present work introduces the first study on the P-wave morphological variability two hours preceding the onset of paroxysmal atrial fibrillation (PAF). The development of non-invasive methods able to track P-wave ...
Splitting the P-Wave: Improved Evaluation of Left Atrial Substrate Modification after Pulmonary Vein Isolation of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Bertomeu-González, Vicente; Hornero, Fernando; Quesada, Aurelio; Alcaraz, Raúl; Rieta, J J (MDPI AG, 2022-01)

[EN] Atrial substrate modification after pulmonary vein isolation (PVI) of paroxysmal atrial fibrillation (pAF) can be assessed non-invasively by analyzing P-wave duration in the electrocardiogram (ECG). However, whether ...
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. ...
Time Variability of P-wave Features from the Preoperative Electrocardiogram Predicts Recurrence After Catheter Cryoablation of Atrial Fibrillation

Ruiz, Antonio; Arias, Miguel A.; Puchol, Alberto; Pachón, Marta I.; Rieta, J J; Alcaraz, Raúl (IEEE, 2020-10-30)

[EN] Pulmonary vein isolation is nowadays the cornerstone for the treatment of paroxysmal atrial fibrillation (AF). However, its success rate is not as high as clinically desirable, and repeated procedures are often required. ...
