Atrial flutter is a type of abnormal heart rhythm that occurs when the heart’s two upper chambers (the atria) beat too fast. It is usually caused by a re-entry circuit, which is an electrical current that travels around the heart in a loop. This causes a rapid and regular heartbeat.
Treatment
Atrial flutter can often be treated with medications, such as beta blockers, calcium channel blockers, and digoxin. However, medications can only control the symptoms, not cure the condition. The most effective treatment for atrial flutter is an electrical procedure called cardioversion, which can be done in a hospital. During this procedure, an electric shock is used to reset the heart’s rhythm back to normal.
Lifestyle Changes
Making lifestyle changes can help reduce the frequency and severity of atrial flutter episodes. These changes include eating a healthy diet, exercising regularly, avoiding stress, not smoking, and avoiding caffeine, alcohol, and other stimulants.
Other Treatments
If medications and lifestyle changes do not work, or if the condition is severe, a catheter ablation or surgical ablation may be recommended. During a catheter ablation, a long, thin tube is inserted into a blood vessel in the leg and guided up to the heart. A special tool is then used to destroy the abnormal electrical pathways that cause the atrial flutter. In a surgical ablation, the surgeon makes an incision in the chest and uses a special tool to destroy the abnormal pathways. These procedures can help reduce or eliminate atrial flutter episodes.
