Atrial flutter is usually paroxysmal and only rarely chronic. Untreated persons with atrial flutter and no disease of the AV junction usually have a 2:1 AV conduction response with an atrial rate of about 300 beats/min and a ventricular rate of 150 beats/min. Over time, atrial flutter usually degenerates into AF.
Read moreWhat is the ECG finding of atrial flutter?
ECG in atrial flutter. The ECG shows regular flutter waves (F-waves; not to be confused with f-waves seen in atrial fibrillation) which gives the baseline a saw-tooth appearance . Atrial flutter is the only diagnosis causing this baseline appearance, which is why it must be recognized on the ECG.
Read moreIs atrial flutter serious?
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.

Read moreWhat AFib looks like on ECG?
This means an ECG showing atrial fibrillation will have no visible P waves and an irregularly irregular QRS complex . The ventricular rate is frequently fast, unless the patient is on AV nodal blocking drugs such as beta-blockers or non-dihydropyridine calcium channel blockers.
Read moreWhat is left atrial flutter?
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 moreHow do you calculate atrial flutter rate?
By counting the number of QRS complexes and multiplying by six , the number per minute can be calculated — because 10 seconds times six equals 60 seconds, or 1 minute. This is a better method when the QRS complexes are irregular, as during atrial fibrillation, in which case the RR intervals may vary from beat to beat.
