Does a calcium channel blocker help or hurt the dijoxin benefitd?
It depends a little on why you take it. Digoxin inhibits a active channel in your heart that pumps potassium and sodium ions. It changes the gradient of the ions and leads to increased calcium in the heart. Increased calcium inside the heart cells can lead to a more forceful contraction and improve symptoms and decrease hospitalizations in people with heart failure.
It also increases "vagal tone," the arm of your autonomic nervous system responsible for slowing your heart rate.
It is typically used in two settings:
1. heart failure patients to decrease hospitalizations and improve symptoms
2. fast heart rhythms to slow down heart rate (like atrial fibrillation)
