FAQs Coping with A-Fib: A-Flutter
I received an email from Jack Owens asking about Atrial Fiutter and our coverage of the topic on A-Fib.com. Here’s what he asked me, followed by my reply:
“I have A-Flutter and not A-Fib. Can I assume that most of the topics discussed on this site apply to both A-Fib and A-Flutter? I would very much like to see more information on your site about A-Flutter. There are a lot of us out here with it. Your web site is the best by far I have found on this subject.”
Atrial Flutter a Form of A-Fib
Consider Atrial Flutter as a milder, more organized form of A-Fib. However, because Flutter is more organized and regular, it often makes the ventricles beat faster. Sometimes it’s harder to control the pulse rate of Flutter compared to A-Fib.
During a catheter ablation for A-Fib, as the electrophysiologist (EP) ‘isolates’ A-Fib areas, the patient’s heart often progresses or improves into Atrial Flutter, then into tachycardia, and finally into normal sinus rhythm (NSR).






Flutter and Atypical Flutter
There are basically two forms of Atrial Flutter:
• Atrial Flutter: Comes from the right atrium and is easily isolated by what is called a ‘Caviotricuspid Isthmus line ablation’ of the right atrium. This is a very simple procedure which can take as little as 10 minutes to complete. It’s often done in addition to an ablation for Atrial Fibrillation either before or after leaving the left atrium.
• Atypical Flutter: A second type is often called “atypical Flutter.” At the end of a more complex catheter ablation, sometimes a patient remains in ‘atypical’ Flutter. This Flutter circuit can be difficult to map and isolate and is often one of the hardest arrhythmias to find and fix.
Often when I talk with patients with atypical flutter, I recommend them to Master EPs who have special mapping and ablation skills and more experience.
Flutter Can Be Considered a Form of A-Fib or Related to A-Fib
Almost every article on A-Fib.com can also relate to Atrial Flutter. It’s true, we often don’t mention Atrial Flutter specifically. But Atrial Flutter is often related to and can be a form of Atrial Fibrillation.
In fact, a patient’s Atrial Flutter may mask that they also have Atrial Fibrillation. Likewise, as many as half of all patients who have an ablation specifically for Atrial Flutter, later develop Atrial Fibrillation.
