An Efficient Hybrid Methodology for Local Activation Waves Detection under Complex Fractionated Atrial Electrograms of Atrial Fibrillation

Osorio, Diego; Vraka, Aikaterini; Quesada, Aurelio; Hornero, Fernando; Alcaraz, Raúl; Rieta, J J (MDPI AG, 2022-07)

[EN] Local activation waves (LAWs) detection in complex fractionated atrial electrograms (CFAEs) during catheter ablation (CA) of atrial fibrillation (AF), the commonest cardiac arrhythmia, is a complicated task due to ...
Comparative Study of Methods for Cycle Length Estimation in Fractionated Electrograms of Atrial Fibrillation

Osorio, Diego; Vraka, Aikaterini; Moreno-Arribas, José; Bertomeu-González, Vicente; Alcaraz, Raúl; Rieta, J J (MDPI AG, 2022-10)

[EN] Atrial cycle length (CL) is an important feature for the analysis of electrogram (EGM) characteristics acquired during catheter ablation (CA) of atrial fibrillation (AF), the commonest cardiac arrhythmia. Nevertheless, ...
Far-field contributions in multi-electrodes atrial recordings blur distinction between anatomical and functional reentries and may cause imaginary phase singularities A computational study

Martínez-Mateu, Laura; Romero Pérez, Lucia; Saiz Rodríguez, Francisco Javier; Berenfeld, Omer (Elsevier, 2019)

[EN] Background Atrial fibrillation (AF) is the most common cardiac arrhythmia and the most important cause of embolic stroke, requiring new technologies for its better understanding and therapies. Recent approaches to ...
The stationary wavelet transform as an efficient reductor of powerline interference for atrial bipolar electrograms in cardiac electrophysiology

Martinez-Iniesta, Miguel; RÓDENAS, JUAN; Rieta, J J; Alcaraz, Raul (IOP Publishing, 2019-07)

[EN] Objective :The most relevant source of signal contamination in the cardiac electrophysiology (EP) laboratory is the ubiquitous powerline interference (PLI). To reduce this perturbation, algorithms including common ...
Waveform Integrity in Atrial Fibrillation: The Forgotten Issue of Cardiac Electrophysiology

Martinez-Iniesta, Miguel; Rodenas, Juan; Alcaraz, Raúl; Rieta, J J (Springer-Verlag, 2017)

[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 ...
