Digoxin for Fast Heart Rates
How It Works
Digoxin helps slow the heart rate by reducing the number of electrical impulses that pass through (but do not originate in) the atrioventricular (AV) node into the lower heart chambers (ventricles).
Digoxin can also strengthen ventricular contractions so that the heart is able to pump more blood with each beat.
Why It Is Used
Digoxin slows heart rate and strengthens heart contractions in people who have a fast heart rate. Digoxin can also be used to treat heart failure.
How Well It Works
Digoxin may improve symptoms by slowing the heart rate and strengthening the heart contractions in people who have heart failure. Digoxin is often not very effective for preventing supraventricular tachycardia.1 Beta-blockers and calcium channel blockers are most often tried first.
High doses may cause digoxin poisoning. Symptoms of digoxin poisoning include:
