Radionuclide determination of cardiac outputs and indices.
A radionuclide procedure for the determination of cardiac output is presented. Cardiac outputs estimated by the proposed method are compared to those obtained by the temperature dilution method during right heart catheterization. A new index of cardiac performance is also presented: cardiac output as a percentage of total blood volume. This index is determined by a totally external count-based procedure.
