  1. 1. Aspects on Cardiac Pumping

    Författare :Marcus Carlsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac Pumping; Ventricular Function; Fysiologi; Physiology;

    Sammanfattning : Cardiac pumping physiology is important for understanding the pathophysiology of patients with cardiac disease. MRI gives the opportunity to measure volumes and flow non-invasively with high accuracy and precision. This thesis examines some aspects on cardiac pumping physiology. LÄS MER

  3. 3. Mitral annulus motion in left ventricular pumping

    Författare :Kent Emilsson; Peter Carlens; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiology; Kardiologi;

    Sammanfattning : This thesis focus on the role of the mitral annulus motion (MAM) versus outer contour changes in the short axis, in left ventricular (LV) pumping. The influence of atrial contraction on LV dimensions and volumes and the relation between MAM and ejection fraction (EF) in sinus rhythm and in atrial fibrillation was also studied. LÄS MER

  4. 4. Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake

    Författare :Katarina Steding Ehrenborg; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; respiratory indices; peak oxygen uptake; heart failure; cardiac magnetic resonance imaging; exercise physiology;

    Sammanfattning : Although the athlete's heart has been of interest for over 100 years, further characterization of the athletes heart is needed in order to understand how training affects cardiac dimensions and function. Few studies have investigated the effects of training in female athletes and few have compared males and females. LÄS MER

  5. 5. Imaging and modeling the cardiovascular system

    Författare :Elira Maksuti; Michael Broomé; Anna Bjällmark; Matilda Larsson; Martin Ugander; Patrick Segers; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cardiac pumping; diastolic function; hemodynamics; modeling; simulation; arterial stiffness; ultrasound; shear wave elastography.; Medicinsk teknologi; Medical Technology; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Cardiac pumping;

    Sammanfattning : Understanding cardiac pumping function is crucial to guiding diagnosis, predicting outcomes of interventions, and designing medical devices that interact with the cardiovascular system.  Computer simulations of hemodynamics can show how the complex cardiovascular system is influenced by changes in single or multiple parameters and can be used to test clinical hypotheses.
