Can the Apple Watch differentiate between Atrial Flutter and Atrial Fibrillation?

Actually, I think atrial flutter would also be considered an irregular rhythm. However, I appreciate your answer because it sounds like the Watch cannot tell the difference between Atrial flutter and fibrillation, which is my main concern. Thanks.

Thank you. However, I think the upper and lower chambers could be out of rhythm with atrial flutter as well, since with Flutter, the atrial chamber may beat 4 times for every one ventrical beat. But it sounds like the watch can't tell flutter and fibrillation apart. I think fibrillation is more serious because it is more likely to cause a stroke. I have both, and that is why I was hoping the watch could tell the difference.

Thank you!!! That was an extremely accurate and helpful response because I have been deliberating over having an ablation to correct A-Fib. I will discuss with my Doctor, but I suspect that most of my Apple Watch 6 Atrial Fibrillation indications are actually Atrial Flutter, as during a 30 second Watch ECG, my Heart Rate is still very low, I have no symptoms, and I had been previously diagnosed by a Doctor as having Atrial Flutter with a premature beat. Your answer correlates exactly with what I have read, and with what I believe is my situation. Thanks again!
