Atrial flutter is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit in the heart causes the upper chambers (atria) to pump very rapidly. Atrial flutter is important not only because of its symptoms but because it can cause a stroke that may result in permanent disability or death .
Read moreWhat is the cause of atrial flutter?
It’s caused by an abnormal electrical circuit in the upper chambers of the heart (atria) that makes the atria beat quickly and flutter instead of fully squeezing. It can result in fast heart rates and a heart that doesn’t work as well as it should.
Read moreWhat is atrial flutter on ECG?
Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute ; the atrial rate in atrial fibrillation is 400 to 600 bpm.
Read moreAre P waves present in atrial flutter?
This is because the P waves (flutter waves ) in atrial flutter occur at about 250-350 per minute (usually around 300). At this rate, it can appear that there is a P wave in front of each QRS and a T wave after each QRS.15 Kas 2016
Read moreWhat is the difference between AF and atrial flutter?
In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles , so you may have four atrial beats to every one ventricular beat.
