  1. 1. Analysis of Electrocardiograms Using Artificial Neural Networks

    Författare :Bo Hedén; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; Lead reversal.; Myocardial infarction; Computer-assisted; Expert system; Electrocardiography; ECG-diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Most conventional ECG interpretation programs use decision tree logic for interpretation of the ECG. The performance is generally good but can be improved. Artificial neural networks represent a new computer method, which has proved to be of value in pattern recognition and classification tasks. LÄS MER

  3. 2. Alternative Lead Systems for Diagnostic Electrocardiography: Validation and Clinical Applicability

    Författare :Annika Welinder; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. LÄS MER

  4. 3. Fetal ECG waveform analysis for intrapartum monitoring

    Författare :Isis Amer-Wåhlin; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; Obstetrics; gynaecology; andrology; cerebral metabolism; microdialysis; implementation; fetal asphyxia; intrpartum monitoring; Fetal ECG; Cardiotocography; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : Waveform analysis of the fetal electrocardiogram has been studied since the early seventies from both physiological, signal processing and clinical aspects. It has been found to contain more useful information than the mere detection of RR-intervals (fetal heart rate), e.g. LÄS MER

  5. 4. New Methods for Automated Interpretation of Electrocardiograms and Lung Scintigrams

    Författare :Holger Holst; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Decision Support System Clinical ; Image Processing Computer-Assisted ; Radionucleotide Imaging; Pulmonary Embolism; tomography; radiology; Neural Networks Computer ; Electrocardiography; Clinical physics; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The principal purposes of the studies reported in this thesis were to develop new methods to make computerised decision support systems in medicine both more reliable and fully automated. These aims were pursued in the belief that the solution to these problems will lead to an increased clinical use of such systems resulting in benefit to both patient and physician. LÄS MER

  7. 5. Chronic atrial fibrillation in man. Activation, organisation and characterisation

    Författare :Magnus Holm; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECG spectral analysis; Preferential conduction; Organisation; Conduction velocity; Refractoriness; Mechanisms; Activation pattern; Chronic; Fibrillation; Human; Atrium; Open-heart surgery; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. LÄS MER
