1
Q
Why do we Give Digoxin
A
To increase cardiac Contractility
2
Q
Mechanisms of Digoxin
A
Inhibits Na+/K+ channel, leading to increased Ca2+ retention and increased muscle contraction
3
Q
Risks of Digoxin
A
Levels of Ca2+ can build up and lead to dysrhytmias
4
Q
Other drugs given in cardiac failure
A
Decrease Pre-load, decrease Afterload and increase activity of the heart
5
