  1. 16. Evaluation of isovolumic myocardial motions in human subjects using tissue velocity echocardiography

    Författare :Britta Lind; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Colour-coded tissue velocity imaging (TVE) with Echocardiography is an established method for evaluation of the global cardiac function and of the regional myocardial movements. The TVE-technique allows measurements of velocity and deformation variables from any discrete point in the myocardial wall during the cardiac cycle with high temporal and longitudinal spatial resolution.

  3. 17. Use and Misuse of Oxytocin During Delivery

    Författare :Maria Jonsson; Ulf Hanson; Solveig Nordén Lindeberg; Ingrid Östlund; Lennart Nordström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Obstetrics and gynaecology; Obstetrik och gynekologi; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Obstetric malpractice claims, concerning delivery during a period of eight years, were analysed for motives behind disciplinary actions, and for the frequency of inappropriate oxytocin use.Failure to respond to signs of foetal distress, injudicious use of oxytocin and a failure to effect a timely delivery were the recurrent problems that accounted for the majority of disciplinary actions.

  4. 18. Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI

    Författare :Belén Casas Garcia; Tino Ebbers; Jonas Lantz; Petter Dyverfeldt; Carljohan Carlhäll; Frans van de Vosse; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D Flow MRI; Computational modelling; Blood flow; Hemodynamics;

    Sammanfattning : Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease.

  5. 19. Growth, Accumulation, Crisis : With New Macroeconomic Data for Sweden 1800-2000

    Författare :Rodney Edvinsson; Karl Gratzer; Satya Datta; Olle Krantz; Jan Bohlin; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GDP; employment; national accounts; Sweden; crisis; growth; capital; capitalism; accumulation; profit; surplus; economic history; growth theory; Marxism; long wave theory; business cycle; depression; recession; Economic history; Ekonomisk historia;

    Sammanfattning : This dissertation has two main objectives. The first one is to construct historical macroeconomic series for Sweden using a consistent method throughout the relevant periods, and which rely on modern methods of national accounting. LÄS MER

  7. 20. New approaches to monitoring of cardiac function

    Författare :Emil Söderqvist; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; left ventricle; pressure and volume; Medical engineering; Medicinsk teknik;

    Sammanfattning : Left ventricular pumping performance may be described by intraventricular pressure and volume variables, usually presented as a pressure-volume plot. However, on-line monitoring of left ventricular pressure and volume with high temporal resolution requires the use of an invasive catheter technique such as, for example, the conductance catheter method.
