BACKGROUND Left ventricular rotation and twist can be assessed noninvasively by speckle tracking echocardiography. We sought to characterize the effects of acute load change and change in inotropic state on rotation parameters as a measure of left ventricular (LV) contractility. METHODS Seven anesthetised juvenile pigs were studied, using direct(More)
Left ventricular function's relation to load, experimental studies in a porcine model. Abstract 4 ABSTRACT Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force. Many modern echocardio-graphic parameters which have been announced as describing ventricular function(More)

BACKGROUND Tissue velocity echocardiography is increasingly used to evaluate global and regional cardiac function. Previous studies have suggested that the quantitative measurements obtained during ejection are reliable indices of contractility, though their load-sensitivity has been studied in different settings, but still remains a matter of controversy.(More)
