RubidiumS6 distribution was used to estimate the distribution of myocardial blood flow in albino rats. The results indicate that the perfusion rates of the left ventricle, apex and interventricular septum are all substantially identical, averaging 2.6 to 2.9 ml./Gm. of tissue/min. The value for the right ventricle is 3.2 ml./Gm./min. The implications of these findings for the measurement of coronary blood flow by the nitrous oxide method are discussed.
