  1. 1. 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

  3. 2. Studies on malignant ventricular tachyarrhythmias and their treatment with an implantable defibrillator

    Författare :Bengt Sandstedt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implantable cardioverter defibrillator; ventricular fibrillation; ventricular tachycardia; predischarge test; defibrillation threshold; discrimination; electrogram morphology; aortic stenosis; hypertrophy; noradrenalin;

    Sammanfattning : Aims: To investigate the hemodynamic, metabolic and autonomic effects of ventricular fibrillation per se during maintained circulation. To study the defibrillation threshold (DFT) and efficacy of a new and thinner ICD lead (DSP) compared with the standard lead (C). LÄS MER

  4. 3. Biomarkers of inflammation in atrial fibrillation

    Författare :Julia Aulin; Jonas Oldgren; Ziad Hijazi; Lars Wallentin; Håkan Wallén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; biomarkers; inflammation; inflammatory biomarkers; oral anticoagulation; heart failure; left ventricular function; ejection fraction; risk assessment; risk prediction; interleukin 6 IL-6 ; C-reactive protein CRP ;

    Sammanfattning : Atrial fibrillation (AF) is common and associated with increased risk of stroke, heart failure (HF) and mortality. Inflammation is linked to AF.The overall aim of this thesis was to investigate inflammatory activity and cardiovascular outcomes and mortality in patients with AF on effective oral anticoagulation.

  5. 4. Catheter ablation for atrial fibrillation : effects on rhythm, symptoms and health-related quality of life

    Författare :Anna Björkenheim; Dritan Poçi; Deirdre Lane; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; catheter ablation; symptoms; quality of life;

    Sammanfattning : Background: AF ablation is an increasingly used treatment in patients with AF to improve patient-reported outcomes (PROs). Atrioventricular junction ablation (AVJA) is a palliative treatment option in therapy refractory AF that improves PROs but renders the patient pacemaker dependent. LÄS MER

  7. 5. Aspects of Intraoperative Ablation for Atrial Fibrillation

    Författare :Birgitta Johansson; Göteborgs universitet; []
    Nyckelord :atrial fibrillation; intraoperative ablation; radiofrequency; cryo; epicardial; quality of life; atrial function; predictors of rhythm;

    Sammanfattning : Background: Increasing knowledge about mechanisms that trigger and maintain atrial fibrillation (AF) has influenced the possibilities for treatment and even cure of AF. The surgical Cox Maze III procedure is still the gold standard for the curative treatment of AF. LÄS MER
