Abstract

Utilizing a coincidence counting system for the measurement of myocardial uptake of an 84-rubidium indicator, resting coronary blood flow (CBF) was measured in 33 normal subjects. The average CBF was 269 ± 61 ml/min/total heart. This represented 5.2 ± 1.6% of the simultaneous cardiac output. Fourteen normal subjects had resting and exercising CBF measurements. The change in CBF with exercise was statistically significant (0.005 > P > 0.001). The characteristics of the method are discussed in relationship to possible clinical applications for the measurement of CBF.
