A

May cause weaker contractility

25
Effects of Muscarinic Agonists on Heart Contractility
May cause weaker contractility
26
Effects of Muscarinic Antagonists on Heart Contractility
May cause stronger contractility
27
Effects of Alpha Agonists on Blood Pressure
Increases pressure (Constriction of blood vessels)
28
Effects of Alpha Antagonists on Blood Pressure
Decreases pressure, especially upon standing (Dilation of blood vessels)
29
Effects of Beta 1 and Beta 2 Agonists on Blood Pressure
Usually increases pressure (Reduction of renin)
30
Effects of Beta 1 and Beta 2 Antagonists on Blood Pressure
Usually decreases pressure mildly
31
Effects of Muscarinic Agonists on Blood Pressure
Decreases via dilation of blood vessels and decreased heart rate
32
Effects of Muscarinic Antagonists on Blood Pressure
Minor increase via constriction of blood vessels
