Atrial flutter is a cardiac arrhythmia, or an abnormal heart rhythm, that occurs when the atria of the heart beat faster than normal. In atrial flutter, the atria beat at a rate of around 300 beats per minute, or five times faster than the normal rate of around 60 to 100 beats per minute. Atrial flutter is not a regular rhythm.
Atrial flutter is caused by an electrical circuit within the heart that becomes very fast and causes the atria to beat at a rapid rate. This rapid heartbeat can cause a number of symptoms, such as palpitations, lightheadedness, and shortness of breath. It can also cause the heart to pump less blood to the rest of the body, which can lead to a decrease in blood pressure. Atrial flutter can also lead to a dangerous condition called stroke, which is caused by a blood clot that forms in the heart and travels to the brain.
Atrial flutter can be treated with medications, electrical cardioversion, or a procedure called ablation, which uses heat or cold to destroy the abnormal electrical pathways in the heart. In some cases, surgery may be necessary to correct the underlying cause of the arrhythmia.
Atrial flutter is a serious condition that requires medical attention. It is important to talk to your doctor if you experience any of the symptoms of atrial flutter. Your doctor can diagnose the condition and recommend treatment that is right for you.
