  1. 16. Cardiac involvement in familial amyloidosis with polyneuropathy

    Författare :Peter Eriksson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloidosis; arrhythmias; cardiac pacing; cardiac radionuclide; imaging; echocardiography; electrocardiography; pathology;

    Sammanfattning : Familial amyloidosis with polyneuropathy (FAP) is a neuropathic form of heredofamilial systemic amyloidosis. Clusters of patients have been reported predominantly from Portugal, Japan and Sweden. The present study examines the involvement of the heart in individuals with the Swedish variety of FAP. LÄS MER

  4. 18. 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

  5. 19. Optimized Pacing Strategies in Cross-Country Skiing and Time-Trial Road Cycling

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; John Rasmussen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; numerical simulation; equations of motion; MMA; cross-country skiing; cycling; Optimering; numerisk simulering; rörelseekvationer; MMA; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the analysis and optimization of pacing strategies in cross-country skiing and time-trial road cycling. In locomotive sports, it is well known that variable pacing strategies using changes in the distribution of power output are beneficial when external forces vary along the way. LÄS MER

  7. 20. Computer-based modeling and simulation in the analysis of cardiac arrhythmias and cardiac pacing

    Författare :Hans Åhlfeldt; Linköpings universitet; []
    Nyckelord :arrhythmogenic mechanisms; modulated parasystole; phase response curve; pacemaker follow-up; modeling; simulation; MEDICINE; MEDICIN;

    Sammanfattning : Most systems for ECG analysis deal with QRS classification and arrhythmia detection but do not address the problem of finding the underlying mechanism responsible for the manifest arrhythmia. Although it is possible to distinguish among different arrhythmogenic mechanisms on the cellular level, it is far more difficult in the clinic based on ECG recordings. LÄS MER
