  1. 1. Estimation of respiratory frequency from Heart Rate Variability

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Ågärd; [2023]
    Nyckelord :time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER

  3. 2. Finding well-being between heartbeats : An empirical study correlating subjective well-being with high frequency heart rate variability

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Nathalie Helle; [2021]
    Nyckelord :subjective well-being; heart rate variability; high-frequency heart rate variability; correlational study; cognitive neuroscience;

    Sammanfattning : Physical health can be measured in several ways both based on subjective experiences and with objective tools. However, mental health can only be measured through subjective experiences and sensations, which can be biased. LÄS MER

  4. 3. Binary classification of HRV signals

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Rebecca Lütz; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Heart rate variability, commonly abbreviated as HRV, displays the variance between consecutive heartbeats. This variance occurs naturally but can change due to stress and problems with the cardiac system. HRV is therefore widely used for medical research. LÄS MER

  5. 4. Survival Analysis Using Time-Frequency Analysis of Heart Rate Variability During Exercise

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Carl Sjögren; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Heart rate variability as an indicator of increased morbidity has been established in previous studies. It is defined by different frequency bands, corresponding to different biological mechanisms. This thesis aims to study heart rate variability indices in the time-frequency domain through extraction from the UK Biobank dataset. LÄS MER

  7. 5. Heart rate variability : A possible measure of subjective wellbeing?

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Kajsa Boman; [2018]
    Nyckelord :Subjective wellbeing; HRV; heart rate variability; measurement; cognitive neuroscience;

    Sammanfattning : Wellbeing and subjective wellbeing (SWB) has become some the most important goals of our time, both individually and societally. Thus, there is a need for reliable ways to measure SWB, as concerns regarding many current measures have been raised. LÄS MER
