System For Open-chest, Multidirectional Electrical Defibrillation
(Sociedade Brasileira de Engenharia Biomédica, 2016)
Proceso de atención de enfermería en adulto mayor de 80 años de edad con fibrilación ventricular.
(Babahoyo: UTB-FCS, 2021, 2021)
Modulation of spatial variance of ventricular repolarization after myocardial infarction
(Elsevier, 2017-04)
Myocardial infarction (MI) alters spatial features of thesurface electrocardiogram. Spatial variance of the T-wave (SVT )describes the interlead dispersion about a mean T-wave morphology. SVTwas linked to arrhythmiavulnerability ...
Probability of ventricular fibrillation: allometric model based on the ST deviation
(BioMed Central, 2011-01)
Background
Allometry, in general biology, measures the relative growth of a part in relation to the whole living organism. Using reported clinical data, we apply this concept for evaluating the probability of ventricular ...
Improved complete ensemble EMD: A suitable tool for biomedical signal processing
(Elsevier, 2014-11)
The empirical mode decomposition (EMD) decomposes non-stationary signals that may stem from nonlinear systems, in a local and fully data-driven manner. Noise-assisted versions have been proposed to alleviate the so-called ...
Melatonin for a Healthy Heart Rhythm
(IntechOpen, 2020)
Melatonin is a promising cardioprotective agent. Its increase during the night is associated with healthy cardiovascular function. On the other hand, reduced levels of melatonin are related to diseases. Aging and ...
Análisis de validación de un modelo estadístico de regresión logística mediante un algoritmo de aprendizaje de máquina supervisado para predecir la mortalidad en pacientes con fibrilación ventricular.
(Universidad de Guayaquil. Facultad de Ciencias Matemáticas y Físicas. Carrera de Ingeniería en Sistemas Computacionales., 2022-04-07)
La arritmia cardíaca (también llamadas palpitaciones) son problemas en el ritmo cardíaco, que ocurren
cuando los impulsos eléctricos que coordinan los latidos cardíacos no funcionan correctamente, lo que hace
que el ...
Melatonin receptor activation protects against low potassium‐induced ventricular fibrillation by preserving action potentials and connexin‐43 topology in isolated rat hearts
(Wiley Blackwell Publishing, Inc, 2019-09)
Hypokalemia prolongs the QRS and QT intervals, deteriorates intercellular coupling, and increases the risk for arrhythmia. Melatonin preserves gap junctions and shortens action potential as potential antiarrhythmic mechanisms, ...
Correlation between functional and ultrastructural substrate in Brugada syndrome
(Elsevier, 2016-05)
Brugada syndrome (BS) was reported for the first time in 1992 and is associated with an ST-segment elevation in the right precordial leads in the absence of any demonstrable structural heart disease, as well as with sudden ...
Characterization of the in vivo cardiac electrophysiologic effects of high-dose cocaine in closed-chest, anesthetized dogs with normal hearts
(Sociedade Brasileira de Cardiologia - SBC, 2003-07-01)
OBJECTIVE: To characterize the cardiac electrophysiologic effects of cocaine. METHODS: In 8 dogs (9-13 kg), electrophysiologic parameters and programmed stimulation were undertaken using transvenous catheters at baseline, ...
