  1. 6. Sudden cardiac death among the young in Sweden 1992-1999 : from epidemiology to support of the bereaved

    Författare :Aase Wisten; Johan Herlitz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; Symptoms; Sudden cardiac death; Young; Prevention; Sweden; Electrocardiogram; Forensic diagnosis; Athletic activities; Risk factors; Familiy; Bereavement; Public health science; Folkhälsovetenskap;

    Sammanfattning : Sudden cardiac death (SCD) in a young person is a rare but tragic event, and the potential of prevention is unknown. The aim of this thesis is to contribute to the prevention by analysing SCD in the young in Sweden during the period 1992-1999. Data of SCD in the young based on a national registry is not previously reported. LÄS MER

  3. 7. Detection and Classification in Electrocardiac Signals

    Författare :Magnus Åström; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

    Sammanfattning : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. LÄS MER

  4. 8. The oesophageal route in clinical electrocardiology

    Författare :Steen Pehrson; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; oesophageal electrocardiogram; cardiac pacing; Transoesophageal stimulation; arrhythmias; non-invasive electrophysiology; atrial fibrillation; supraventricular tachycardia; Kardiovaskulära systemet;

    Sammanfattning : The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. LÄS MER

  5. 9. Signal Modeling and Detection in Nephrologic and Cardiac Applications

    Författare :Kristian Solem; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart rate turbulence HRT ; Heart rate variability HRV ; Electrocardiogram ECG ; Pulse oximetry.; Biomedical signal processing; Intradialytic hypotension; Hemodialysis; Ectopic beats;

    Sammanfattning : This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. LÄS MER

  7. 10. Noninvasive characterization of patients with monomorphic ventricular tachycardia and ventricular fibrillation using the signal-averaged electrocardiogram. A study on late potentials and spectral turbulence in patients with ischemic heart disease and in healthy subjects

    Författare :Christer Gottfridsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal-averaged ECG; ventricular tachycardia; ventricular fibrillation; late potentials; spectral turbulence; bundle branch block;

    Sammanfattning : Many people die suddenly from sustained ventricular tachyarrhythmias caused by ischemic heart disease, and the sudden death may be the first presentation of heart disease. If the patients at risk of ventricular tachyarrhythmia could be identified, some patients may be saved. LÄS MER
