  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. Association of a Wristband PPG and an ECG Sensor - Analysis, Synchronization and Robustness

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Mattéo Hochart; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Context: The CardioHolter, developed by Kaunas Institute of Technology, Lithuania, has been used in previous studies on cardiovascular behavior at the Department of Biomedical Engineering at Lund University. This equipment associates two finger photoplethysmography (PPG) sensors and an electrocardiogram (ECG) sensor. LÄS MER

  4. 3. Classifying Heart Rate Variability Data using Multitaper Spectrum Analysis

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Heidi Mach; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Heart rate variability (HRV) is the variation between two consecutive heartbeats. The irregular variability in this interval can indicate different health issues such as stress. The goal of this project is to correctly classify if a HRV signal comes from a resting state or a state which is affected by stress related stimuli. LÄS MER

  5. 4. Cardiovascular effects of exposure to biodiesel exhaust

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Youna Marc-Derrien; [2021]
    Nyckelord :photoplethysmography; electrocardiography; signal processing; pulse decomposition analysis; heart rate variability; pulse transit time; biodiesel; arterial stiffness; Technology and Engineering;

    Sammanfattning : Context: Urban air pollution is considered a significant factor contributing to increased respiratory and cardiovascular mortality in cities. Many studies focused on the relationship between exposure to diesel exhaust and human health effects, demonstrating the toxicity of such gases. LÄS MER

  7. 5. Automatic Prediction of Human Age based on Heart Rate Variability Analysis using Feature-Based Methods

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Yusur Al-Mter; [2020]
    Nyckelord :Supervised learning; Classification; Ensemble; Support Vector Machines; Heart Rate Variability; Extreme Gradient Boosting; Random Forest;

    Sammanfattning : Heart rate variability (HRV) is the time variation between adjacent heartbeats. This variation is regulated by the autonomic nervous system (ANS) and its two branches, the sympathetic and parasympathetic nervous system. LÄS MER
