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 ...
Characterization of complex fractionated atrial electrograms by Sample Entropy: An international multi-center study

Cirugeda Roldán, Eva María; Novak, Daniel; Kremen, Vaclav; Cuesta Frau, David; Keller, Matthias; Luik, Armin; Srutova, Martina (MDPI, 2015-11)

Atrial fibrillation (AF) is the most commonly clinically-encountered arrhythmia. Catheter ablation of AF is mainly based on trigger elimination and modification of the AF substrate. Substrate mapping ablation of complex ...
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, ...
Detection of Dominant Reentries in Multichannel Electrograms of Atrial Fibrillation

Vraka, Aikaterini; Osorio, Diego; Bertomeu-González, Vicente; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2019-11-23)

[EN] Algorithms developed so far for the detection of local activation waves (LAWs) in electrograms (EGMs) of atrial fibrillation (AF) analyze each channel of the catheter separately, while dominant reentries of AF are ...
Dynamic approximate entropy electroanatomic maps detect rotors in a simulated atrial fibrillation model

Ugarte, Juan P.; Orozco-Duque, Andrés; Tobon Zuloaga, Catalina; Kremen, Vaclav; Novak, Daniel; Saiz Rodríguez, Francisco Javier; Oesterlein, Tobias; Schmitt, Clauss; Luik, Armin; Bustamante, John (Public Library of Science, 2014-12)

There is evidence that rotors could be drivers that maintain atrial fibrillation. Complex fractionated atrial electrograms have been located in rotor tip areas. However, the concept of electrogram fractionation, defined ...
Short-Time Estimation of Fractionation in Atrial Fibrillation with Coarse-Grained Correlation Dimension for Mapping the Atrial Substrate

Vraka, Aikaterini; Hornero, Fernando; Bertomeu-Gonzalez, Vicente; Osca, Joaquin; Alcaraz, Raul; Rieta, J J (MDPI AG, 2020-02-19)

[EN] Atrial ¿brillation (AF) is currently the most common cardiac arrhythmia, with catheter ablation (CA) of the pulmonary veins (PV) being its ¿rst line therapy. Ablation of complex fractionated atrial electrograms (CFAEs) ...
