The injection of indicator into the pulmonary artery and left atrium, with systemic arterial sampling, resulted in similar levels of output. The flow levels after injection into the left atrium were not higher, but, on the contrary, were some-what lower than those after injection into the pulmonary artery. These data validate the assumption that measurements of left ventricular output may be made via injection of indicator into the right heart.
