| ofthe digitalis glycosides only _____ is used to any extent its action in the failing heart is complex | Digoxin[Lanoxin] |

| believed to bind to and inhibit the sodium-potassium ATPase ion transport system | Digoxin |
| hypokalemia decreases the effectiveness of this pump inhibits the sodium potassium ATPase pump and prevents sodium from pumping out of the cell increase of sodium inside of the cell | Digoxin |
