Ultrasound determination of left ventricular position for volume angiography.
The reliability of angiographically determined left ventricular (LV) volume is in part dependent upon the accuracy of the determination of the position of the left ventricular (LV) chamber in rehtion to the x-ray image intensifier. A new device is described which utilizes available ultrasound techniques and equipment to ascertain readily the height of the LV above the table top with the patient...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولNon-invasive left ventricular volume determination by two-dimensional echocardiography.
Twenty patients undergoing routine left ventricular single-plane angiography have been investigated by an ultrasonic triggered B-scan technique to provide a two-dimensional cross-sectional image of the left ventricle in end-systole end-diastole. An area-length method has been used to establish the correlation between the angiographic and the echocardiographic assessments of left ventricular cha...
متن کاملDetermination of left ventricular end-systolic pressure-volume relationships by the conductance (volume) catheter technique.
Using a multielectrode conductance catheter to estimate continuous left ventricular volume we determined the end-systolic pressure-volume relationship (ESPVR) in situ in open-chest anesthetized dogs. Dogs (n = 8) were studied in the control state and after pharmacologic sympathectomy (hexamethonium) and surgical vagotomy both before and after the administration of dobutamine. ESPVR was measured...
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...
