Atrial flutter is a type of abnormal heart rhythm that can last from minutes to weeks. The duration of atrial flutter depends on many factors, including the underlying cause, the type of flutter, and the individual's response to treatment. Generally, atrial flutter can last for days or weeks without treatment, but it can be corrected with medication or a procedure called ablation.
Causes of Atrial Flutter
Atrial flutter is caused by an electrical malfunction in the heart's atrium, which is the upper chamber of the heart. It occurs when the electrical signals that control heart rhythm become erratic. This can be due to a variety of conditions, such as coronary artery disease, heart valve disease, high blood pressure, chronic lung disease, and certain medications.
Types of Atrial Flutter
Atrial flutter can be either type I or type II. Type I flutter is characterized by a rapid, regular pattern of electrical signals that cause the atrium to contract abnormally. Type II flutter is characterized by a slower, more organized pattern of electrical signals that cause the atrium to contract abnormally.
Treatment of Atrial Flutter
Atrial flutter can be treated with medications, such as beta-blockers or calcium channel blockers, which can help to slow the heart rate and normalize the rhythm. In some cases, a procedure called catheter ablation may also be used to correct the abnormal heart rhythm. During this procedure, a catheter is inserted into a vein in the leg and guided to the heart, where it is used to destroy the abnormal electrical pathways that are causing the flutter.
Outlook
Atrial flutter can usually be successfully treated if it is identified and addressed quickly. The prognosis is generally good, although some people may experience relapses of the condition. It is important to follow your doctor's instructions for taking any medications and to attend follow-up appointments to monitor your condition.
