Análisis tiempo-frecuencia de la fibrilación ventricular. Estudio experimental

Revista Española de Cardiología, 2006
Introduction and objectives. The analysis of frequency variability during ventricular fibrillation has yielded inconsistent results. We used an experimental model of ventricular fibrillation, with a short timescale, to analyze variations in frequency and their associated spatial distribution. Methods.

Tiempo, espacio y frecuencia en la fibrilación ventricular

Revista Española de Cardiología, 2006
Ventricular fibrillation (VF) is the main immediate cause of sudden, unexpected cardiac death. It appears in the electrocardiogram (ECG) as an aperiodic, irregular rhythm, giving the impression that electrical activation of the ventricles is highly complex and disordered.

Módulo Tiempo-Frecuencia para el Estudio de los Procesos Cognitivos

2013
Cognitive functions and their manifestations in behavior and subjective experience, arise from the activity of the brain. It is therefore extremely useful to attempt to localize brain functions. This has potential clinical importance since it might be possible to relate it to abnormalities in specific brain regions.
