Analysis of an electrocardiographic multilead system by means of artificial neural networks: study of repolarization during premature ventricular stimulation
(SciTepress, 2016)
The ventricular repolarization dispersion (VRD) has been shown to increase with premature stimulation. Moreover, several differences between left ventricular and right ventricular, such as the anatomic properties and ...
Aging disrupts the temporal organization of antioxidant defenses in the heart of male rats and phase shifts circadian rhythms of systolic blood pressure
(Springer, 2021-12)
Aging is one of the main risk factors for cardiovascular diseases, and oxidative stress is a key element responsible for the development of age-related pathologies. In addition, the alteration of circadian rhythms also ...

Association between ventricular filling patterns and the extent of late enhancement on magnetic resonance imaging in patients with hypertrophic cardiomyopathyAsociación entre patrones de llenado ventricular y extensión del realce tardío por resonancia magnética en pacientes con miocardiopatía hipertrófica
(Ediciones Doyma, S.L., 2017-01)
Objective To explore the relationship between ventricular filling curves and the extent of late enhancement on cardiac magnetic resonance imaging (MRI) in patients with hypertrophic cardiomyopathy. Material and methods We ...
Mitochondrial Bioenergetics During Ischemia and Reperfusion
(Springer, 2017)
During ischemia and reperfusion (I/R) mitochondria suffer a deficiency to supply the cardiomyocyte with chemical energy, but also contribute to the cytosolic ionic alterations especially of Ca2+. Their free calcium ...
