The left ventricular contractility of the rat heart is modulated by changes in flow and <FONT FACE=Symbol>a</font>1-adrenoceptor stimulation

Myocardial contractility depends on several mechanisms such as coronary perfusion pressure (CPP) and flow as well as on <FONT FACE="Symbol">a</font>1-adrenoceptor stimulation. Both effects occur during the sympathetic stimulation mediated by norepinephrine. Norepinephrine incre...
