In patients with severe ventricular systolic dysfunction, elevated serum noradrenaline is a sign of a bad prognosis independent of haemodynamic andejectionfractionparameters.
From theCambridge English Corpus
Thus, enddiastolic and end-systolic volumes are computed from their respective data sets andejectionfractionis calculated from these values.
From theCambridge English Corpus
Three-dimensional echocardiography also allows the calculation of ventricular volumes andejectionfraction without the need for geometric assumptions, since it reconstructs the entire ventricular cavity.
From theCambridge English Corpus
Right ventricularejectionfractionwas calculated as stroke volume divided by end-diastolic volume.
From theCambridge English Corpus
Estimates of right ventricular volume andejectionfractionwere compared to determinations made using magnetic resonance imaging.
From theCambridge English Corpus
On first pass radionuclide ventriculography, mean right ventricularejectionfractionwas almost identical in the two groups.
From theCambridge English Corpus
For calculation ofejectionfraction, the largest and smallest ventricular areas were taken as diastole and systole respectively.
From theCambridge English Corpus
Normal right ventricularejectionfractionat our institution (mean + 2 standard deviations) is 0.65 + 0.16 (range 0.49 to 0.81).
From theCambridge English Corpus
Theejectionfractionis usually depressed for one to three days during which time there can be a substantial inotrope requirement.
From theCambridge English Corpus
Regression of the diastolic volume is more marked than that of the endsystolic volume, leading to a decreased right ventricularejectionfraction.
From theCambridge English Corpus
All patients had a normal global left ventricular function with a medianejectionfractionof 0.66 (0.59-0.72) before and 0.64 (0.58-0.7) after surgery.
From theCambridge English Corpus
There was no significant change inejectionfractionor tricuspid regurgitation.
From theCambridge English Corpus
Cardiac performance, as assessed by the stroke volume, cardiac output, andejectionfractionwere reduced in the pathologic outcome group.
From theCambridge English Corpus
The heart also improves in contractility, resulting in a largerejectionfraction, a larger stroke volume and increased maximal cardiac output.
From theCambridge English Corpus
Neither were significant differences seen in left ventricular percent fractional shortening, left ventricularejectionfraction, and mean rate corrected velocity of circumferential fiber shortening.
From theCambridge English Corpus
Where left ventricularejectionfractionis less than 40%, we recommend abstinence from strenuous or competitive sports.
From theCambridge English Corpus
The right ventricularejectionfractionimproved from 0.39+0.04 to 0.6+0.03 (p<0.001).
