Afib is caused by multiple electrical impulses firing in the atria simultaneously, while A-flutter is caused by a single electrical impulse circulating in the atria.
Afib is characterised by an irregular heart rate, while A-flutter typically results in a more regular heart rate.

Afib is typically characterised by an irregularly irregular rhythm on an ECG, while A-flutter is characterised by a "sawtooth" pattern.
Afib is more likely to cause fatigue and A-flutter more likely to cause chest discomfort.
Afib can be either paroxysmal (intermittent) or persistent, while A-flutter is typically persistent.
Afib is more common in older adults and those with underlying heart disease, while A-flutter is more commonly seen in younger, healthy individuals.
A-flutter is more likely to require cardioversion (a procedure to restore normal heart rhythm) and Afib more likely to require medication or ablation.
Afib is associated with an increased risk of stroke and other complications, while A-flutter is generally considered less risky.
Afib and A-flutter can occur together, but Afib is more common than A-flutter.
Afib is more likely to recur after treatment than A-flutter.
