| Question | Answer |
| Class | Cardiac glycoside |
| MOA | Inhibits Na+ K+ pump=increaed Na and Ca in the intracellular space=increased cardiac contractility (+inotropic effect) |
| MOA | decreases vagal tone=decreased SA node firing,prolongs conduction through AV=(-chronotropic) |
| MOA | In a-fib and A-flutter it decreases the number of atrial impulses(-chronotropic) |
| MOA | improves CO (decreases baroreceptor response=decreased SNS discharging=decreased BP due to (+inotropic effects) |
| Indications | Controls ventricular rate in A-fib/A-flutter |
| Indications | psvt |
| Indication | CHF |
| Indication | Cardiogenic Shock |
