Which medication is referred to as digitalis and aids in heart rhythm control?

The medication known as digitalis is specifically Digoxin, which is derived from the foxglove plant. Digoxin works by affecting the heart and is primarily used to treat various heart conditions, including atrial fibrillation and heart failure. It helps to control heart rate and improve the efficiency of heart contractions, which is essential for patients who experience issues with heart rhythm.

The other medications listed are utilized for different purposes: Coumadin is an anticoagulant used to prevent blood clots, Divalproex sodium is primarily an anticonvulsant used to treat seizures and bipolar disorder, and Hydrochlorothiazide is a diuretic that helps manage hypertension and edema but does not directly affect heart rhythm like Digoxin does. Understanding these distinctions is crucial in medication management and ensures proper treatment for cardiovascular conditions.
