[EN] In the management of atrial fibrillation (AF), electrical cardioversion (ECV) is a common treatment. Although its initial success rate is high, many patients present AF recurrence after some weeks or months. Hence, ...
[EN] Catheter ablation (CA) is a commonly used treatment for persistent atrial fibrillation (AF). Since its medium/long-term success rate remains limited, preoperative prediction of its outcome is gaining clinical interest ...
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 ...
[EN] The analysis of coronary sinus (CS) electrograms (EGMs) during catheter ablation (CA) of atrial fibrillation (AF) is highly important for AF substrate evaluation. However, channels of the CS catheter may be affected ...

Nonlinear analysis has emerged as a novel methodology for the processing of physiological time series over the past few decades because biological systems and processes are inherently complex, nonlinear, and non-stationary. ...
[EN] A normal cardiac activation starts in the sinoatrial node and then spreads throughout the atrial myocardium, thus defining the P-wave of the electrocardiogram. However, when the onset of paroxysmal atrial fibrillation ...
[EN] Current wearable electrocardiogram (ECG) recording systems have great potential to revolutionize early diagnosis of paroxysmal atrial fibrillation (AF). They are able to continuously acquire an ECG signal for long ...
[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 ...
[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. ...
BackgroundThe study of atrial conduction defects associated with the onset of paroxysmal atrial fibrillation (PAF) can be addressed by analyzing the P wave from the surface electrocardiogram (ECG). Traditionally, signal-averaged ...

[EN] The detection of hypertension (HT) is of great importance for the early diagnosis of cardiovascular diseases (CVDs), as subjects with high blood pressure (BP) are asymptomatic until advanced stages of the disease. The ...

[EN] Coronary sinus (CS) catheterization is critical during catheter ablation (CA) of atrial fibrillation (AF). However, the association of CS electrical activity with atrial substrate modification has been barely investigated ...
Ruiz, Antonio; Arias, Miguel A.; Pachón, María Inmaculada; Langley, Philip; Rieta, J J; Alcaraz, Raúl(IEEE, 2019-11-23)
[EN] Detailed analysis of the electrocardiogram (ECG) recording allows to obtain relevant information about the heart state and its behavior. Indeed, the P-wave study has proven to be helpful in diagnosing many atrial ...
[EN] Surgical ablation (SA) is the most effective procedure
to terminate atrial fibrillation (AF) in patients requiring
concomitant open-heart surgery. However, considering the
great stress provoked in the patient¿s heart, ...

[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. ...
[EN] Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with an increasing prevalence of about 15% in the elderly. Despite other alternatives, catheter ablation is currently considered as the ...
This work introduces for the first time the application of wavelet entropy (WE) to detect episodes of the most common cardiac arrhythmia, atrial fibrillation (AF), automatically from the electrocardiogram (ECG). Given that ...
