Assessment of mitral regurgitation by dye dilution curves.


Hering (1829, 1832) obtained circulation times by detecting injected samples of potassium ferrocyanide by the Prussian Blue reaction, as quoted by Dow (1956). Stewart (1894) extended the work of Hering and was able to measure the cardiac output by a quantitative determination of the dilution of a solution of salt injected intravenously. It has taken many… (More)
