In many cases, no underlying cause for atrial flutter is identified. In some patients, atrial flutter may occur in patients with prior open heart surgery, even occurring many years before. Some patients with atrial flutter have other heart conditions or a history of high blood pressure.
Is atrial flutter dangerous?
When a heart doesn’t beat as it should, it doesn’t effectively pump blood to the organs of the body. This may result in the symptoms described above or the patient may have minimal or no symptoms. Atrial flutter may be associated with an increased risk of stroke. The risk of stroke is assessed using the CHADS2 scoring system.
