    Desarrollo y validación de algoritmos para el estudio de la variabilidad de la frecuencia cardíaca en adultos mayores
    (2015) Parra Orellana, Freddy Andres; Wong de Balzan, Sara; Palacio Baus, Kenneth Samuel
    This work is part of the project: Heart Rate Variability (HRV) and Insulin Sensibility among the Senior Population of Cuenca (Variabilidad de la Frecuencia Cardiaca (VFC) y Sensibilidad a la Insulina en la Población Adulta Mayor de Cuenca), funded and promoted by the Prometo Program and the Research Direction of the University of Cuenca (Dirección de Investigación de la Universidad de Cuenca – DIUC). The main goal of this thesis was to develop algorithms aimed to study the Heart Rate Variability. The tasks performed in this work include: i) the acquisition of SCP-ECG electrocardiographic registers from a senior population set, ii) the development of a platform aimed to integrate ECG registers with clinic and demographic information of studied subjects; iii) ECG processing by making use of the Pan-Tompkins QRS detector and artifact filtering in order to obtain RR series, and iv) the application of non-parametric methods (PSD and Hamming) and parametric methods (Burg) for temporal and spectral estimation, in addition to temporal parameter (SDRR, SMRRD) computation and frequency parameter (LF,HF, LF/HF) computation from the HRV. The development of this project makes use of a Graphic User Interface (GUI) called UCUENCAViewer ANALISIS VFC, which will allow researchers to analyze senior population’s HRV. Additionally, this tool will be available for teaching purposes and able to be used in future research.
