  1. 1. Finding the QRS Complex in a Sampled ECG Signal Using AI Methods

    University essay from KTH/Fysik

    Author : Jeanette Marie Victoria Skeppland Hole; [2023]
    Keywords : ECG; ECG-analysis; QRS detector; Artificial Intelligence; Machine Learning; Deep neural networks; Long short-term memory; Convolutional neural network; Multilayer perceptron; EKG; EKG-analys; QRS detektor; Artificiell intelligens; Maskininlärning; Djupa neurala nätverk; Long short-term memory; Convolutional neural network; Multilayer perceptron;

    Abstract : This study aimed to explore the application of artificial intelligence (AI) and machine learning (ML) techniques in implementing a QRS detector forambulatory electrocardiography (ECG) monitoring devices. Three ML models, namely long short-term memory (LSTM), convolutional neural network (CNN), and multilayer perceptron (MLP), were compared and evaluated using the MIT-BIH arrhythmia database (MITDB) and the MIT-BIH noise stress test database (NSTDB).

  3. 2. Self-supervised representation learning from electrocardiogram data for medical applications

    University essay from Lunds universitet/Matematik LTH

    Author : Matilda Andersson; [2023]
    Keywords : Self-supervised learning; Deep learning; Cardiovascular disease; Electrocardiogram; ECG; SimCLR; BYOL; VICReg; Mathematics and Statistics;

    Abstract : Cardiovascular diseases are the leading cause of death worldwide, increasing yearly. However, many abnormalities in heart cycles can be discovered and treated years before the onset of diseases. But in most societies, regular health checkups are a concept reserved for cars, not humans. READ MORE

  4. 3. Estimation of respiratory frequency from Heart Rate Variability

    University essay from Lunds universitet/Matematisk statistik

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

    Abstract : 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. READ MORE

  5. 4. Detection of driver sleepiness during daylight and darkness

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Johanna Eklind; Amanda Meyerson; [2023]
    Keywords : Driver sleepiness; daylight; darkness; driving simulator study; ecg; eog; signal processing; exploratory analysis; statistical analysis; ANOVA; biomedical engineering;

    Abstract : Driving sleepiness is a serious problem worldwide. It is of interest to develop reliable sleepiness detection systems to implement in vehicles, and for such a system both physi-ological data and driver performance data can be used. READ MORE

  6. 5. Optimal Multitaper Spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Markus Ydreskog; [2023]
    Keywords : Time-frequency analysis; Multitaper spectrogram; Optimization; Wigner distribution; Mathematics and Statistics;

    Abstract : Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. READ MORE
