What medications control heart rate in atrial fibrillation?

By Mayo Clinic Staff

Atrial fibrillation is a common heart rhythm disorder. Treatments for atrial fibrillation may include medications and other interventions to try to alter the heart's electrical system.

You may be prescribed medications to control your heart rate and restore it to a normal rate. Heart rate control can be achieved through several medications.

The medication (Lanoxin) generally controls heart rate well at rest, but not as well during activity. Most people require additional or alternative medications, such as calcium channel blockers or beta blockers.

Beta blockers may cause side effects such as worsening of heart failure and low blood pressure (hypotension). Calcium channel blockers also can cause side effects and may need to be avoided if you have heart failure or low blood pressure.

In some cases, if medications aren't effective, you may need a more invasive procedure to control your heart rate.
