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 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.
Read moreHow do you calculate atrial rate?
To determine atrial rate, count the number of P waves in 6 seconds and multiply by 10 . To determine the ventricular rate, count the number of QRS complexes in 6 seconds and multiply by 10. Rates greater than 100 beats per minute (bpm) are considered tachycardia. Rates slower than 60 bpm are considered bradycardia.
Read moreDoes atrial flutter have QRS?
The ECG shows atrial flutter with narrow QRS complexes signifying recruitment of the ventricles using the His-Purkinje conduction system. The flutter waves are seen as regular continuous undulations in multiple ECG leads at a rate of ≈290 cycles per minute.

There are four main types of atrial fibrillation—paroxysmal, persistent, long-term persistent, and permanent atrial fibrillation.
