Ventricular pressure-volume curve indices change with end-diastolic pressure.
Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from a...
متن کاملVentricular response to a pressure load. Left ventricular function curves in intact animal.
• The normal left ventricular response to progressive proximal aortic obstruction has three phases: (1) a phase of complete compensation in which, following transitory elevations of end-diastolic ventricular pressure (EDVT) and end-diastolic ventricular volume (EDVV), the peak ventricular pressure (PVP) is increased and cardiac output is maintained though end-diastolic ventricular pressure and ...
متن کاملEffects of chronic right ventricular volume and pressure loading on left ventricular performance.
The effects of chronic right ventricular (RV) distension on left ventricular (LV) funiction were assessed in dogs 3 weeks after pressure and volume loading of the RV lhad been produced by the emplacement of a constricting band around the pulmonary artery and the creation of tricuspid insufficiency. This resulted in ascites, RV hypertrophy and dilatation, an increase in RV end-diastolic pressure...
متن کاملLeft ventricular diastolic pressure-volume relations in man.
Diastolic function of the left ventricle was analysed in patients with different cardiac diseases: acute and chronic volume overload (in aortic and mitral incompetence), pressure overload and inappropriate ventricular hypertrophy (aortic stenosis and hypertrophic cardiomyopathy), congestive cardiomyopathy, and constrictive pericarditis. Most patients were receiving digitalis therapy at the time...
