  1. 6. Left ventricular function's relation to load, experimental studies in a porcine model

    Author : Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart function; preload; afterload; contractility; myocardial tissue velocity; speckle tracking; Anaesthetics and intensive care; Anestesiologi och intensivvård; Cardiology; kardiologi;

    Abstract : Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force.  Many modern echocardiographic parameters which have been announced as describing ventricular function and contractile status, may be confounded by uncontrolled and unmeasured load.

  5. 10. Arterial pulse wave analysis. With special reference to vasoactive and anaesthetic drugs and to heart lung interactions

    Author : Staffan Söderström; Göteborgs universitet; []
    Keywords : pulse; blood pressure physiology; hypertension; aged; vasodilation; ventricular function; left; nitroglycerin; coronary disease; artificial respiration; fentanyl.;

    Abstract : In the young systolic arterial pressures (SAP) are higher in the radial artery than in the proximal aorta. Due to increased large artery stiffness and early pulse wave reflection aortic SAP increases more with age than peripheral SAP. READ MORE
