Atrial flutter is an arrhythmia, or abnormal heart rhythm, that affects the upper chambers of the heart. The most commonly used drug to treat atrial flutter is called a beta-blocker. Beta-blockers work by blocking the hormones that increase heart rate and pressure, allowing the heart to beat slower and more regularly. Examples of beta-blockers used to treat atrial flutter include atenolol, metoprolol, propranolol, and esmolol.
Other medications, such as calcium channel blockers and digoxin, may also be used to treat atrial flutter. Calcium channel blockers work by preventing calcium from entering the cells of the heart, slowing the heart rate. Digoxin works by strengthening the heart's contractions, helping it to beat more regularly.
In some cases, atrial flutter may be treated with cardioversion, a procedure in which an electric shock is used to reset the heart's rhythm. Surgery may also be necessary to correct the underlying cause of atrial flutter.
The drug of choice for treating atrial flutter will depend on the individual patient and the severity of their condition. It is important to discuss all treatment options with your doctor before beginning any medication.
