Aplicación software para la reconstrucción del Vectorcardiograma a partir de la señal ECG y cálculo de métricas. Aplicación a pacientes con HTP.

Requena Calabuig, Natàlia (Universitat Politècnica de València, 2021-12-27)

[ES] Los pacientes que padecen hipertensión pulmonar sufren un aumento de presión en las arterias pulmonares, lo que conduce a la hipertrofia y a la la dilatación crónica de ambos, la aurícula y el ventrículo derechos. ...
Evaluation and assessment of clique arrangements for the estimation of omnipolar electrograms in high density electrode arrays: an experimental animal model study

Ruiperez-Campillo, Samuel; Crespo, Marina; Tormos Ferrando, Álvaro; Guill Ibáñez, Antonio; Cebrián Ferriols, Antonio José; Alberola, Antonio; Heimer, Jakob; Chorro, Francisco J.; Millet Roig, José; Castells, Francisco (Springer Dordrecht, 2023-09)

[EN] High-density catheters combined with Orientation Independent Sensing (OIS) methods have emerged as a groundbreaking technology for cardiac substrate characterisation. In this study, we aim to assess the arrangements ...
Mini Peltier Cell Array System for the Generation of Controlled Local Epicardial Heterogeneities

Segarra, Izan; Cebrián Ferriols, Antonio José; Ruiperez-Campillo, Samuel; Tormos Ferrando, Álvaro; Chorro, Francisco Javier; Castells, Francisco; Alberola, Antonio; Millet Roig, José (IEEE, 2023-07-27)

[EN] The present study aims to design and fabricate a system capable of generating heterogeneities on the epicardial surface of an isolated rabbit heart perfused in a Langendorff system. The system consists of thermoelectric ...
Non-invasive characterisation of macroreentrant atrial tachycardia types from a vectorcardiographic approach with the slow conduction region as a cornerstone

Ruipérez-Campillo, Samuel; Castrejón, Sergio; Martínez, Marcel; Cervigón, Raquel; Meste, Olivier; Merino, José Luis; Millet Roig, José; Castells, Francisco (Elsevier, 2021-03)

[EN] Background and objectives: Macroreentrant atrial tachyarrhythmias (MRATs) can be caused by different reentrant circuits. The treatment for each MRAT type may require ablation at different sites, either at the right ...
Performance assessment of electrode configurations for the estimation of omnipolar electrograms from high density arrays

Castells, Francisco; Ruiperez-Campillo, Samuel; Segarra, Izan; Cervigon, Raquel; Casado-Arroyo, Rubén; Merino, José Luis; Millet Roig, José (Elsevier, 2023-03)

[EN] Objective: The aim of this study is to propose a method to reduce the sensitivity of the estimated omnipolar electrogram (oEGM) with respect to the angle of the propagation wavefront. Methods: A novel configuration ...
Segmenting computed tomograms for cardiac ablation using machine learning leveraged by domain knowledge encoding

Feng, Ruibin; Deb, Brototo; Ganesan, Prasanth; Tjong, Fleur V.Y .; Rogers, Albert J.; Ruiperez-Campillo, Samuel; Somani, Sulaiman; Clopton, Paul; Baykaner, Tina; Rodrigo, Miguel; Zou, James; Haddad, Francois; Zaharia, Matei; Narayan, Sanjiv M. (Frontiers Media SA, 2023-10-02)

[EN] Background: Segmentation of computed tomography (CT) is important for many clinical procedures including personalized cardiac ablation for the management of cardiac arrhythmias. While segmentation can be automated by ...
The art of selecting the ECG input in neural networks to classify heart diseases: a dual focus on maximizing information and reducing redundancy

Ramírez, Elisa; Ruiperez-Campillo, Samuel; Casado-Arroyo, Rubén; Merino, José Luis; Vogt, Julia E.; Castells, Francisco; Millet Roig, José (Frontiers Media SA, 2024-10-07)

[EN] Background and Objectives Accurate diagnosis of cardiovascular diseases often relies on the electrocardiogram (ECG). Since the cardiac vector is located within a three-dimensional space and the standard ECG comprises ...
Vector Field Heterogeneity for the Assessment of Locally Disorganised Cardiac Electrical Propagation Wavefronts From High-Density Multielectrodes

Pancorbo, Lucía; Ruiperez-Campillo, Samuel; Tormos, Álvaro; Guill Ibáñez, Antonio; Cervigón, Raquel; Alberola, Antonio; Chorro, Francisco Javier; Millet Roig, José; Castells, Francisco (Institute of Electrical and Electronics Engineers, 2024)

[EN] High-density multielectrode catheters are becoming increasingly popular in cardiac electrophysiology for advanced characterisation of the cardiac tissue, due to their potential to identify impaired sites. These are ...
