Digoxin and contractility
WebDigoxin and dobutamine are used to treat different heart conditions.; Digoxin is used for treating adults with mild to moderate congestive heart failure and for treating abnormally rapid atrial rhythms (atrial fibrillation, atrial flutter, atrial tachycardia).It also is used for increasing myocardial contractility in pediatric patients with heart failure. WebDigoxin is a cardiac glycoside. Digoxin inhibits the sodium potassium adenosine triphosphatase (ATPase) pump, thereby increasing intracellular calcium and enhancing cardiac contractility. This agent also acts …
