A Noninvasive Technique for the Study of Cardiac Hemodynamics Utilizing C15O2Inhalation

Abstract: A new technique for the study of cardiac hemodynamics is described which utilizes single-breath inhalation of C15O2 (T 1/2 = 124 sec.) and the recording of activity vs. time curves with scintillation counters placed externally over the left ventricle and right lung.
