  1. 21. Implantable cardioverter defibrillator treatment in patients with hypertrophic cardiomyopathy

    Författare :Peter Magnusson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disease with various clinical manifestations, including sudden cardiac death, which can be prevented by an implantable cardioverter defibrillator (ICD). Aims: The general aim of this thesis was to elucidate different aspects of ICD treatment in patients with HCM. LÄS MER

  3. 22. Phase Transitions in Large Oscillator Lattices

    Författare :Per Östborn; Antikens kultur och samhällsliv; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; phase transition; limit cycle oscillator; frequency entrainment; synchronization; sinus node; classical mechanics; Mathematical and general theoretical physics; arrhythmia; gravitation; quantum mechanics; relativity; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Östborn;

    Sammanfattning : This thesis deals with large networks of limit cycle oscillators. A limit cycle oscillator is a dynamical system that has a periodic attractor in phase space, and is defined in continuous time. To each such oscillator one can associate a natural frequency. LÄS MER

  4. 23. 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. 24. Implantable devices in heart failure : studies on biventricular pacing and continuous hemodynamic monitoring

    Författare :Frieder Braunschweig; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Implantable devices; congestive heart failure; biventricular pacing; hemodynamic monitoring; ambulatory; hospitalizations; positron emission tomography; stress; blood flow; loop diuretics; natriuretic peptides; hemodynamics.;

    Sammanfattning : Chronic heart failure is a highly symptomatic syndrome associated with increasing prevalence, frequent hospital admissions and high treatment costs. Despite recent advances in drug therapy, morbidity and mortality are still high. LÄS MER

  7. 25. Atrioventricular synchronous pacing in hypertrophic obstructive cardiomyopathy

    Författare :Fredrik Gadler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HOCM; pacing; LVOTobstruction; quality of life;

    Sammanfattning : The study addresses major issues of cardiac pacing in hypertrophic obstructive cardiomyopathy (HOCM). The influence of ventricular pacing site and atrioventricular (AV)-delay on left ventricular outflow tract (LVOT) gradient. LÄS MER
