Validity of indicator-dilution determinations of cardiac output in patients with mitral regurgitation.
mHE indicator-dilution method has been widely employed for determination of cardiac output since its introduction by Stewart' and Hamilton and associates.2 The effect of unrecognized recirculation of indicator particles upon the primary indicator time-concentration curve has caused concern as to whether this method may be employed in such conditions as mitral regurgitation3' 4and as to whether ...
متن کاملThe normal resting cardiac output: serial determinations by a dye dilution method.
The resting output of the normal heart has been investigated by many workers (Krogh and Lindhard, 1912; Christiansen et al., 1914; Stewart, 1921; Grollman, 1928; Hamilton et al., 1932; Nylin, 1933; Berseus, 1943; McMichael and Sharpey-Shafer, 1944; Cournand et al., 1945; Stead et al., 1945; Werko, 1947; Chapman et al., 1950; Doyle, et al., 1953; Donald et al., 1955; Goodyer et al., 1960; Reeves...
متن کاملThe Mitral Valve Orifice Method for Noninvasive Two - dimensional Echo Doppler Determinations of Cardiac Output DANIEL
We developed and validated a mitral valve orifice method for Doppler cardiac output determination. In 15 open-chest dogs, cardiac output was controlled and measured by a roller pump interposed between the right atrium and pulmonary artery as a right-heart bypass. Left heart flows were measured in the open-chest dog model by Doppler measurements at the mitral valve orifice and compared not only ...

of time the influence of matter on life and mind will gradually become obliterated and replaced by the influence of mind and its transcendent successors in the great steps of creative evolution." Therefore, "the remote successors of man may be free and independent of matter with infinite possibilities of future progress notwithstanding the complete dissolution of the universe." Pure thought, th...
