已经描述了通过记录从心前区注射的碘化 I131 人血清白蛋白的稀释曲线来确定心输出量的技术。通过主要观察心脏的右侧或左侧并通过同位素的快速输送，可以对心输出量的稀释曲线进行定量，而无需对计数器的放置提出严格要求。在对正常患者进行的一系列 26 次测定中，根据同时记录的心前区曲线和抽取的动脉血计算出的心输出量显示，平均一致性在 ± 8% 之内。在对心力衰竭患者进行的 8 次测定中，发现平均偏差为 ± 9%。
Technics for determining the cardiac output by recording the dilution curve of injected iodinated I131 human serum albumin from precordial sites have been described. By viewing predominantly either the right or left side of the heart and by rapid delivery of the isotope, quantitation of the dilution curves for cardiac output has been possible without critical requirements for placement of the counter. In a series of 26 determinations in normal patients cardiac output values calculated from simultaneously recorded precordial curves and withdrawn arterial blood showed an average agreement within ± 8 per cent. In a smaller series of 8 determinations on patients in heart failure, an average deviation of ± 9 per cent was found.
