  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. Plasmakoncentration av hjärtspecifikt troponin I under konvertering med kinidinsulfat hos hästar med förmaksflimmer

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stephanie Brodd; [2019]
    Keywords : Förmaksflimmer; roponin; cTnl; kinidinsulfat; konvertering;

    Abstract : Atrial fibrillation is the most common performance-limiting arrhythmia in horses. In Sweden, atrial fibrillation is treated medically with quinidine sulphate. READ MORE

  4. 3. ECG-derived respiration in atrial fibrillation

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Danilo Sergio Pupo; Luisa Rusconi; [2017]
    Keywords : Technology and Engineering;

    Abstract : In past years, the demand for an indirect extraction of respiration and the interest in a joint study of respiratory and cardiac systems represented the driving forces for the development of Electrocardiogram Derived Respiration (EDR) algorithms. The main advantage of them consists in deriving a sufficiently reliable surrogate respiratory signal by only exploiting the normal electrocardiogram (ECG) equipment, without requiring the common devices used to record respiration, which are cumbersome and expensive, besides to possibly interfere with natural breathing.

  5. 4. Hilbert Transform : Mathematical Theory and Applications to Signal processing

    University essay from Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Måns Klingspor; [2015]
    Keywords : Hilbert transform; Hilbert-Huang transform; Electrocardiography; Electrocardiogram; ECG; EKG; Nonstationary processes; Hilbert spectrum; Modulation; Single-sideband modulation; QRS complex; QRS; QRS detection; SSB;

    Abstract : The Hilbert transform is a widely used transform in signal processing. In this thesis we explore its use for three different applications: electrocardiography, the Hilbert-Huang transform and modulation. For electrocardiography, we examine how and why the Hilbert transform can be used for QRS complex detection. READ MORE

  6. 5. Kammararytmi hos hund : behandling – när och med vad?

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Daniela Mirbt; [2015]
    Keywords : arytmi; ventrikulära extraslag; ambulatorisk elektrokardiografi; antiarytmika; hund; arrhythmia; ventricular premature contractions; ambulatory electrocardiography; antiarrhythmic; dog;

    Abstract : Ventrikulära takyarytmier är den vanligaste typen av rytmrubbningar hos hundar. Ventrikulära extraslag (VES), när depolarisationen utgår från kammaren, är den mildaste formen. Flera VES på rad med en hög hjärtrytm kallas ventrikulär takykardi (VT) och kan utvecklas till livshotande kammarflimmer (VF) då inget blod pumpas ut i kroppen. READ MORE
