Which is worse atrial flutter vs fibrillation?

Atrial flutter is similar to atrial fibrillation , a common disorder that causes the heart to beat in abnormal patterns. People with atrial flutter have a heart rhythm that’s more organized and less chaotic than that of atrial fibrillation. Sometimes you may have episodes of both atrial flutter and atrial fibrillation.20 Kas 2020

Both heart diseases have the potential of becoming serious. However, many doctors and other health care professionals consider atrial flutter to be less serious than atrial fibrillation because flutter symptoms tend to be less severe and flutter waves have a less risk of embolization (clot formation).

Although atrial flutter is usually not life-threatening at first , it does limit how well your heart pumps blood. This can cause a clot to form in your heart. If the clot breaks loose, it could lead to a stroke. Over time, atrial flutter can weaken your heart muscle.
