Atrial proarrhythmic effect of lead as one of the PM10 metal components of air pollution. An in-silico study

Palacio, Laura C.; Pachajoa, Diana C.; Durango-Giraldo, Geraldine; Zapata-Hernández, Camilo; Ugarte, Juan P.; Saiz Rodríguez, Francisco Javier; Buitrago-Sierra, Robison; Tobón, Catalina (Public Library of Science, 2021-10-12)

[EN] Particulate matter (PM) is considered the most severe environmental pollution problem due to its serious effects on human health associated with an increased risk of cardiovascular morbidity and mortality. In this ...
Fibrillatory conduction in a simulated two-dimensional model of human atrial tissue: effect of the interaction of two ectopic foci

Tobón, Catalina; Saiz Rodríguez, Francisco Javier (SAGE Publications, 2019-07)

[EN] Atrial fibrillation (AF) is the most common tachyarrhythmia. It has been demonstrated that extra-stimuli could act as triggers for AF. In many patients it is possible that multiple ectopic foci co-exist, and their ...
Immuno-Electrophysiological Mechanisms of Functional Electrical Connections Between Recipient and Donor Heart in Patients With Orthotopic Heart Transplantation Presenting With Atrial Arrhythmias

Herweg, Bengt; Nellaiyappan, Madhan; Welter-Frost, Allan M.; Tran, Thanh; Mabry, George; Weston, Kathryn; Tobón, Catalina; Saiz Rodríguez, Francisco Javier; Noujaim, Sami; Weston, Mark W. (Ovid Technologies Wolters Kluwer -American Heart Association, 2021-04)

[EN] BACKGROUND: The formation of recipient-to donor atrio-atrial connections (AAC) in patients after orthotopic heart transplantation (OHT) is poorly understood. We sought to investigate the mechanisms of atrial ...
Spontaneous activation under atrial fibrosis: A model using complex order derivatives

Ugarte, Juan P.; Tobón, Catalina; Saiz Rodríguez, Francisco Javier; Mendes Lopes, Antonio; Tenreiro Machado, José A. (Elsevier, 2021-04)

[EN] The computational modeling of the cardiac electrophysiology allows assertive and quantitative study of the atrial fibrosis under fibrillation conditions. The cardiac electrical propagation is described by the so-called ...
The Antimalarial Chloroquine Reduces the Burden of Persistent Atrial Fibrillation

Tobón, Catalina; Palacio, Laura C.; Chidipi, Bojjibadu; Slough, Diana P.; Tran, Thanh; Tran, Nhi; Reiser, Michelle; Lin, Yu-Shan; Herweg, Bengt; Sayad, Dany; Saiz Rodríguez, Francisco Javier; Noujaim, Sami (Frontiers Media SA, 2019-11-27)

[EN] In clinical practice, reducing the burden of persistent atrial fibrillation by pharmacological means is challenging. We explored if blocking the background and the acetylcholine-activated inward rectifier potassium ...
