Cardiac Glycosides

Abstract
To understand better and more deeply appreciate the development of knowledge in this field, it is desirable to begin with the simpler aspects of the action of these glycosides and then to proceed to the more complex and perhaps more fundamental ones. The effects of the cardiac glycosides may be listed as follows:Therapeutic doses have no proved useful therapeutic effect on the normal heart, but have been shown to increase the contractile force of the actively contracting cardiac muscle. They also increase the contractile force of skeletal, venous and arterial smooth muscle. Cardiac output is not increased by the . . .
