Alterations in left ventricular volumes induced by Valsalva manoeuvre.
Five patients were studied with left ventriculography during different phases of the Valsalva manoeuvre. Small doses of contrast medium allowed adequate repetitive visualization of the left ventricle for volume calculation. During strain phase, the volume of the left ventricle decreased by nearly 50 per cent in each case, and stroke volume and cardiac output also dropped strikingly. Release of ...
متن کاملLeft Ventricular Pressure-Volume Alterations
Left ventricular function, pressure-volume relationships, and wall motion were studied by sequential cineventriculography during acute myocardial ischemia, induced by atrial pacing, in 10 subjects. Observations made in this group were contrasted to data obtained during atnal pacing in a smaller normal group. An acute alteration in the pressure-volume relation occurred in five subjects during is...

متن کاملLeft Ventricular Diastolic Performance
We used first-pass radionuclide angiocardiography to assess filling fraction during the first third of diastole, peak filling rate and peak filling rate during the first third of diastole as indexes of left ventricular diastolic performance at rest and after upright bicycle exercise in 32 normal patients and 68 patients with coronary artery disease. The mean filling fraction was unchanged from ...
متن کاملLeft Ventricular Performance
THLIE pharmacologic effects of digitalis preparations on the circulatory system have been the subject of numerous investigations in both animals and man. Recently, studies in dogs 1 and man,2' 3as well as experimental work on the proteins of the contractile element of heart muscle,4 have demonstrated that digitalis directly augments the force of myocardial contraction. Most investigations in ma...
