  1. 11. Relating Heart Rate Variability and Age Using Spectral Estimation Methods

    University essay from Lunds universitet/Matematisk statistik

    Author : Amanda Ledell; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : Heart rate variability (HRV) is a measurable property used to describe the naturally occurring time differences between heartbeats and has shown to help with identifying both physiological and psychological disorders. HRV signals of 97 individuals were analyzed using spectral analysis. READ MORE

  3. 12. Classification of HRV-signals using Time-Frequency Analysis

    University essay from Lunds universitet/Matematisk statistik

    Author : Ante Forsgren; Henrik Kragh; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : Heart rate variability (HRV) is a term within cardiology describing the natu- rally occurring variation of the time interval between heartbeats, and high HRV activity has been linked to both cardiovascular and non-cardiovascular health. This bachelor thesis aims to find differences between HRV-signals where short term physical strain (pain) was induced and HRV-signals where no such strain was applied. READ MORE
