The best medication for a flutter depends on the type of flutter and the cause of the flutter.
If the flutter is due to an arrhythmia, then beta-blockers may be the best medication. Beta-blockers are used to slow the heart rate and decrease the force of the heartbeat, which can help reduce or eliminate the flutter. Common beta-blockers used for this purpose include metoprolol, atenolol, and propranolol.
If the flutter is due to a heart valve disorder, such as mitral valve prolapse, then a calcium channel blocker may be the best medication. Calcium channel blockers, such as diltiazem and verapamil, help to reduce the heart rate and can also help to reduce some of the symptoms associated with valvular disorders.
If the flutter is due to an infection, then an antibiotic may be the best medication. The type of antibiotic prescribed will depend on the specific type of infection causing the flutter.
Finally, if the flutter is due to an underlying medical condition, such as an overactive thyroid, then the best medication would depend on the specific condition. For example, an overactive thyroid may be treated with antithyroid medications, such as propylthiouracil or methimazole.
In summary, the best medication for a flutter depends on the type of flutter and the cause of the flutter. Beta-blockers may be used for arrhythmias, calcium channel blockers may be used for valvular disorders, antibiotics may be used for infections, and medications may be used to treat underlying medical conditions.
