[EN] Atrial tachyarrhythmias present a high prevalence in the developed world, and several studies predict that in the coming decades it will be increased. Micro or macro-reentrant mechanisms of the electrical wavefronts ...
[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 ...
Griol Barres, Israel(Universitat Politècnica de València, 2022-05-30)
[ES] En esta tesis doctoral se propone y evalúa un sistema para detectar señales débiles (weak signals) relacionadas con cambios futuros trascendentales. Si bien la mayoría de las soluciones conocidas se basan en el uso ...
[EN] Introduction and objectives: An analysis was made of the effects of a radiofrequency-induced linear lesion during ventricular fibrillation and the capacity to capture myocardium through high-frequency pacing.
Methods: ...
[EN] Although standard 12-lead ECG is the primary
technique in cardiac diagnostic, detecting different
cardiac diseases using single or reduced number of leads
is still challenging. The purpose of our team, itaca-UPV,
is ...
[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 ...
Pedrón Torrecilla, Jorge(Universitat Politècnica de València, 2015-11-30)
[EN] The behavior of the heart is governed by electrical currents generated in the myocardium, and therefore, the study of the cardiac electrical activity is essential for the diagnosis of cardiac diseases.
The forward ...
[EN] Introduction
Ablation of high dominant frequency (DF) sources in patients with atrial fibrillation (AF) is an effective treatment option for paroxysmal AF. The aim of this study was to evaluate the accuracy of noninvasive ...
Background—Ablation of high-frequency sources in patients with atrial fibrillation (AF) is an effective therapy to restore
sinus rhythm. However, this strategy may be ineffective in patients without a significant dominant ...

[ES] La irrupción de los navegadores electroanatómicos cardiacos en la electrofisiología ha supuesto un desarrollo tecnológico sustancial en los últimos años. Aún así, el conocimiento sobre los mecanismos desencadenantes ...
BackgroundThe dominant atrial frequency is a key parameter for the analysis of atrial fibrillation (AF) from intracardiac recordings. The preprocessing approach employed by Botteron et al. in an early work is able to ...
[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 ...

[EN] ntroduction and objectives
Abnormal QT interval durations and dispersions have been associated with increased risk of ventricular arrhythmias. The present study examines the possible arrhythmogenic effect of inducing ...
[EN] Objective: Auscultation of heart sound recordings or the phonocardiogram (PCG) has been shown to be valuable for the detection of disease and pathologies (Leatham 1975, Raghu et al 2015). The automated classification ...
