The first drug of choice for atrial flutter is typically a beta-blocker. Beta-blockers work by blocking the effects of epinephrine, a hormone that is released in response to stress and can increase the heart rate. By blocking the effects of epinephrine, beta-blockers can help reduce the heart rate and restore normal rhythm. Additionally, beta-blockers can help reduce the risk of stroke or heart attack, as well as lessen symptoms of anxiety and shortness of breath.
Other medications that are used to treat atrial flutter include calcium channel blockers, antiarrhythmic drugs, and anticoagulants. Calcium channel blockers work by blocking calcium from entering the cells of the heart, which helps to slow the electrical signals that cause the abnormal rhythm. Antiarrhythmic drugs work by helping to restore the normal rhythm of the heart and can also help reduce the risk of stroke or heart attack. Anticoagulants work by thinning the blood and preventing the formation of blood clots, which can cause serious complications.
It is important to note that the drugs used to treat atrial flutter vary from patient to patient, and the best course of treatment is determined by a medical professional. Additionally, some medications may have side effects that should be discussed with a doctor.
