  1. 31. Study of Electrochemical Behaviour and Corrosion Resistance of Materials for Pacemaker Lead Applications

    Författare :Andreas Örnberg; Jinshan Pan; Jukka Lausmaa; Ann Cornell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-base alloy; 35N LT; MP35N; Ta; TiN coating; electrochemical behaviour; corrosion resistance; Chemistry; Kemi;

    Sammanfattning : For patients suffering bradycardia, i.e., too slow heart rhythm, the common treatment is having a pacemaker implanted. The pacemaker system consists of the pacemaker and a pacing lead. LÄS MER

  3. 32. Fibromyalgia and self-regulatory patterns : development, maintenance or recovery in women

    Författare :Kerstin Wentz; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fibromyalgia; Psychometric instruments; Dissociation; Repression; Self-loading; Self-regulation; Recovery; MEDICINE; MEDICIN; Fibromyalgi - psykologiska aspekter; Fibromyalgia; Self Concept; pain; self-loading; self-regulation; interviews;

    Sammanfattning : Aims: The overall aim of this thesis was to elucidate psychological processes and development, maintenance or recovery related to fibromyalgia based on in depth interviews. In a next step women with fibromyalgia, women without long-lasting pain and women with long-lasting pain were compared using psychometric instruments selected or developed based on qualitative results.

  4. 33. Kamrateffekter i skolundervisning – En ramfaktorteoretisk analys

    Författare :Pontus Bäckström; Sangeeta Bagga-Gupta; Rebecka Florin Sädbom; Vezir Aktaş; Ulf P. Lundgren; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; compositional effects; peer effects; frame factor theory; structural equation modelling;

    Sammanfattning : In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in this study is that the Frame Factor Theory can be used to explain these mechanisms. LÄS MER

  5. 34. 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. 35. Cardiac Resynchronization Therapy Optimization : Comparison and Evaluation of Non-invasive Methods

    Författare :Elena Sciaraffia; Carina Blomström Lundqvist; Giuseppe Boriani; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac resynchronization therapy; device optimization; left ventricular contractility; Cardiology; Kardiologi;

    Sammanfattning : The general purpose of this thesis was to investigate new cardiac resynchronization therapy (CRT) optimization techniques and to assess their reliability when compared to invasive measurements of left ventricular contractility (LV dP/dtmax).We first assessed whether cardiac output (CO) measured by trans-thoracic impedance cardiography could correctly identify the optimal interventricular (VV) pacing interval while using invasive measurements of LV dP/dtmax as reference.
