Abstract

In the course of our work on the positive inotropic (1) and antiarrhythmic properties (2,3) of angiotensin, it was observed that this short-chain polypeptide had an unusual affinity for rabbit atria in very small concentrations. In this paper, the cardiac stimulant effects of angiotensin will be described over a large concentration range and some of the data obtained in the course of studies on its mechanism of action will be reported.
