If you have received a diagnosis of atrial fibrillation or atrial flutter, you may also be prescribed medications to reduce your risk of stroke.
The following medications may be used to manage an abnormal heart rhythm.
Your heart specialist may prescribe antiarrhythmics to control your heart rate. These medications work by suppressing abnormal electrical signals to the heart. Please notify your doctor if you regularly take over-the-counter medications or herbal supplements. These can trigger arrhythmias and interfere with the effectiveness of antiarrhythmics.
Beta blockers can lower your heart rate and prevent arrhythmias by blocking the effects of stress hormones—such as adrenaline—on the heart. These hormones respond to the effects of stress by increasing the heart rate and cardiac output, or blood flow from the heart.
Calcium channel blockers reduce heart rate by preventing calcium from entering the heart’s cells. Because the heart uses calcium when conducting electrical signals, these medications can slow heart rate in people with certain types of supraventricular arrhythmias.
