  1. 6. 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

  3. 7. Catheter ablation compared to antiarrhythmic drugs in patients with atrial fibrillation : A study focusing on arrhythmic burden and quality of life

    Författare :Victoria Svedung Wettervik; Carina Blomström-Lundqvist; Elena Sciaraffia; Mattias Duytschaever; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Patients with atrial fibrillation (AF) experience symptoms and have impaired health-related quality of life (HRQoL). Rhythm control therapy, including antiarrhythmic drugs (AAD) and catheter ablation for pulmonary vein isolation, aims to relieve symptoms and improve HRQoL. LÄS MER

  4. 8. Surgical treatment of atrial fibrillation : clinical, hormonal and electrophysiological aspects of the maze operation

    Författare :Anders Albåge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Atrial fibrillation (AF) is the most common arrhythmia, associated with significant mortality and morbidity, due to hemodynamic impairment and the increased risk of stroke. Traditional pharmacological treatment may be insufficient or cause intolerable side-effects. LÄS MER

  5. 9. Atrial fibrillation : clinical presentation and management, with special emphasis on magnesium therapy

    Författare :Mats Frick; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :atrial fibrillation; magnesium; arrhythmias; cardioversion; sotalol;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, causing disabling symptoms, risk of thromboembolic events and increased mortality. Some patients with AF are asymptomatic, but to what extent these patients differ from patients with symptoms is unclear. LÄS MER

  7. 10. Sequence and dispersion of repolarization of the right atrium: Implications of repolarization disturbance in atrial fibrillation

    Författare :Zhen Li; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; electroanatomical mapping; monophasic action potential; atrial fibrillation; repolarization; dispersion;

    Sammanfattning : To explore the global sequence and dispersion of repolarization of the right atrium, monophasic action potentials (MAPs) were sequentially recorded from the right atrium using an electroanatomical mapping (CARTO) system in 10 healthy pigs and in 10 patients with (n=6) and without (n=4) paroxysmal atrial fibrillation (PAF) during sinus rhythm, or using two MAP recording catheters in 30 patients with or without PAF (n=15 each) during sinus rhythm, pacing, and programmed stimulation. The dispersion of activation time (AT), repolarization time (RT) and MAP duration (MAPd) were analyzed. LÄS MER
