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 ...
Are Coronary Sinus Features Reflecting the Effect of Catheter Ablation of Atrial Fibrillation as P-waves Do?

Vraka, Aikaterini; Bertomeu-González, Vicente; Hornenro, Fernando; Langley, Philip; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] Atrial substrate alteration due to catheter ablation (CA) of atrial fibrillation (AF) is primarily assessed from P-waves. Nonetheless, how CA affects critical structures is ignored. The aim of the current study is to ...
Atrial low voltage areas: A comparison between atrial fibrillation and sinus rhythm

Andrés Lahuerta, Ana; Roberto, Carlos; Saiz Rodríguez, Francisco Javier; Cano, Óscar; Martínez-Mateu, Laura; Alonso, Pau; Saurí, Assumpció; Quesada, Aurelio; Osca, Joaquín (VM Media Sp zo.o. - VMGroup SK, 2022)

[EN] Background: Atrial fibrosis can promote atrial fibrillation (AF). Electroanatomic mapping (EAM) can provide information regarding local voltage abnormalities that may be used as a surrogate marker for fibrosis. Specific ...
Higher reproducibility of phase derived metrics from electrocardiographic imaging during atrial fibrillation in patients remaining in sinus rhythm after pulmonary vein isolation

Molero-Alabau, Rubén; Soler Torro, Jose Manuel; Martínez Alzamora, Mª Nieves; Climent, Andreu M.; Guillem Sánchez, María Salud (Elsevier, 2021-12)

[EN] Background: Electrocardiographic imaging (ECGI) allows evaluating the complexity of the reentrant activity of atrial fibrillation (AF) patients. In this study, we evaluated the ability of ECGI metrics to predict the ...
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 ...
Variation of P-wave indices in paroxysmal atrial fibrillation patients before and after catheter ablation

Ortigosa, Nuria; Ayala, Guillermo; Cano, Óscar (Elsevier, 2021-04)

[EN] The effects of pulmonary vein isolation in the surface electrocardiogram of patients with paroxysmal atrial fibrillation are analyzed in this paper using non-invasive markers for early detection of the arrhythmia ...
