What are anti-arrhythmic medicines?

Anti-arrhythmic medicines help to restore normal heart rhythm in patients who have conditions like atrial fibrillation that can cause an abnormal heart rhythm. Watch this video to learn more.

Antiarrhythmic medicines may be used to return an irregular heartbeat (arrhythmia) to its normal rhythm, prevent an arrhythmia or control the heartbeat during an arrhythmia. These drugs work mostly by slowing the heart rate or by helping stabilize the heart muscle tissue. Many antiarrhythmic medicines have side effects, and many interact with other medicines. A person taking any of these medicines should talk often with his or her doctor.
