[EN] Cardiac resynchronization therapy (CRT) is an effective treatment for those patients with severe heart failure. Regrettably, there are about one third of CRT "non-responders", i.e. patients who have undergone this ...
Atrial fibrillation (AF) is the most common arrhythmia in routine clinical practice. Despite many years of research, its mechanisms still are not well understood, thus reducing the effectiveness of AF treatments. Nowadays, ...

[EN] Atrial fibrillation disorders are one of the main arrhythmias of the elderly. The atrial and ventricular activities are
decoupled during an atrial fibrillation episode, and very rapid and irregular waves replace the ...
[EN] In this study, we propose a new classification method for early differentiation of paroxysmal and persistent atrial fibrillation episodes, i.e. those which spontaneously or with external intervention will return to ...

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 ...

[ES] En este trabajo se pretende dar respuesta a la necesidad clínica de la evaluación objetiva de la respuesta a terapias de estimulación en el tratamiento de pacientes con Estados Alterados de Conciencia (EAC). Entre un ...
[EN] One of the most powerful techniques to diagnose cardiovascular diseases is to analyze the electrocardiogram (ECG). To increase diagnostic sensitivity, the ECG might need to be acquired using an ambulatory system, as ...
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 ...
[EN] Atrial fibrillation (AF) is nowadays the most common cardiac arrhythmia, being associated with an increase in cardiovascular mortality and morbidity. When AF lasts for more than seven days, it is classified as persistent ...
The ChipCorder ® technology employs a non volatile analog recording technique based on EEPROM technology (i. e. although the signal is time-sampled, its analog voltage is stored in memory cells based on capacitors). This ...
Atrial fibrillation (AF) is the most common form of arrhythmia encountered in clinical practice. Its presence causes a rapid and irregular ventricular response, being the topic of intensive research in rate control therapies ...
[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 ...
The Cox-maze surgery is an effective procedure for terminating atrial fibrillation (AF) in patients requiring open-heart surgery associated with another heart disease. After the intervention, regardless of the patient's ...
[EN] Changes induced by intrauterine growth restriction (IUGR) in cardiovascular anatomy and function that persist throughout life have been associated with a higher predisposition to heart disease in adulthood. Together ...
[EN] The electrocardiogram (ECG) is a physiological signal highly sensitive to disturbances during its acquisition. To palliate this issue, many works have described preprocessing algorithms operating in 12-lead, short-term ...
Mateo, Jorge; Rieta Ibañez, José Joaquín(Elsevier, 2013-02-01)
The most extended noninvasive technique for medical diagnosis and analysis of atrial fibrillation (AF) relies on the surface elctrocardiogram (ECG). In order to take optimal profit of the ECG in the study of AF, it is ...
Alcaraz, Raúl; Rieta, J J(National Cheng Kung University, 2013)
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. ...
