  2. 1. Computer-based detection of cardiac arrhythmias : methods and systems

    Author : Mats-Erik Nygårds; Linköpings universitet; []
    Keywords : Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

    Abstract : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. READ MORE

  4. 2. Outcomes and safety of new techniques for pulmonary vein isolation in patients with paroxysmal and persistent atrial fibrillation : A study based on randomised trials and registries

    Author : David Mörtsell; Carina Blomström-Lundqvist; Stefan Lönnerholm; Isabel Deisenhofer; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; antiarrhythmic drugs; ablation; cryoballoon; radiofrequency; pulmonary vein isolation; quality of life; arrhythmia monitoring; implantable cardiac monitor; atrial fibrillation burden; health economics; Cardiology; Kardiologi;

    Abstract : Atrial fibrillation (AF) is a common disease with a high prevalence in the adult population. Treatment of AF encompasses antiarrhythmic drugs and catheter ablation to reduce symptoms. READ MORE

  5. 3. Photoplethysmography in multiparameter monitoring of cardiorespiratory function

    Author : Anders Johansson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Photoplethysmography (PPG) is an optical, non-invasive method to assess tissue blood volume/perfusion. When measured on human skin, the PPG signal includes both cardiac synchronous variations (AC) and respiratory induced intensity variations (RIIV). READ MORE

  6. 4. Risks and risk monitoring in sotalol therapy for atrial fibrillation

    Author : Hanna Lenhoff; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Atrial fibrillation (AF) stands as the most prevalent arrhythmia, significantly impacting both the prognosis and symptomatology of affected individuals. Healthcare expenditures associated with AF treatment and its related complications, in terms of morbidity and mortality, are substantial. READ MORE

  7. 5. Ventricular repolarization in the human heart : effects of pharmacological and non-pharmacological interventions

    Author : Karolina J. Nowinski; Karolinska Institutet; Karolinska Institutet; []
    Keywords : QT interval; QT dispersion; PTCA; ischemia; T vector loop; AV junctional RF ablation; arrhythmia; sex hormones; hormone replacement therapy; cardiac memory ECG; signal-averaged ECG;

    Abstract : Ventricular arrhythmias is the main cause of sudden cardiac death. A prolonged repolarization might cause such arrhythmias, and an increased understanding about mechanisms is therefore important for their primary and secondary prevention. READ MORE
