Dofetilide effect on human atrial action potential under normal and atrial fibrillation conditions. In silico study
Atrial fibrillation is the most common sustained cardiac arrhythmia. Dofetilide is an antiarrhythmic drug for the treatment of chronic AF that specifically blocks the rapid component of the delayed rectifier potassium ...
Nonlinear measures characterize atrial fibrillatory dynamics generated using fractional diffusion
Computational simulations are used as tool to study atrial fibrillation and its maintaining mechanisms. Phase analysis has been used to elucidate the mechanisms by which a reentry is generated. However, clinical application ...
Comparison between unipolar and bipolar electrograms for detecting rotor tip from 2D fibrillation model using image fusion. A simulation study
The atrial fibrillation (AF) is the most common arrhythmia, which generates the highest costs on clinical systems. Theory of the rotor is one of the most recent approaches to explain the mechanisms that maintain AF. The ...
Feature subset selection and classification of intracardiac electrograms during atrial fibrillation
Several approaches have been adopted for the identification of arrhythmogenic sources maintaining atrial fibrillation (AF). In this paper, we propose a classifier that discriminates between four classes of atrial electrogram ...
Lead (Pb++) effect on human atrial action potential under normal and atrial fibrillation conditions. In silico study
Lead (Pb++) is a toxic agent that can exert adverse effects on the cardiac human health. Pb++ blocks the Ltype Ca++ channels. A decrease in L-type calcium current (ICaL) is an important mechanism favoring atrial fibrillation. ...
Data fusion from multiple stations for estimation of PM2.5 in specific geographical location
Nowadays, an important decrease in the quality of the air has been observed, due to the presence of contamination levels that can change the natural composition of the air. This fact represents a problem not only for the ...
