Is a flutter worse than AFib?

In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles , so you may have four atrial beats to every one ventricular beat.

Atrial flutter is a condition where the atria of the heart rapidly and regularly beat due to an anomaly in the heart’s electrical system that usually results in a tachycardia. It produces feelings like near-fainting, rapid heartbeats (palpitations), mild shortness of breath, and fatigue .

Sometimes, atrial flutter goes away by itself and no further action is needed . If it persists, your doctor may pursue any of the following treatments: Treatment of any underlying conditions.
