The Cardiovascular System
The actual and potential actions of drugs on this system are explicable only by a consideration of the physiology. This will first be discussed in the general terms of cardiac contraction, then the origin and control of cardiac rhythm, and finally those mechanisms which control blood pressure and vascular tone. Each of these will be followed by a consideration of the relevant pharmacological agents.
