Mar 31, 2025 · Atrial flutter is regular, rapid atrial contractions, while atrial fibrillation is irregular, chaotic atrial contractions. Both affect heart rhythm.

Mar 26, 2025 · Atrial flutter happens when the upper chambers beat faster than normal and are coordinated. It is not as common as atrial fibrillation, also known as AFib or AF.

Jul 22, 2021 · In contrast to atrial flutter, atrial fibrillation is a more chaotic rhythm that does not follow one set loop. When the heart's chamber fibrillates, it quivers or shakes, rather than contracting. This …

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.

Oct 2, 2025 · Atrial flutter and atrial fibrillation (AFib) are heart rhythm conditions that occur when the upper chambers of the heart (known as the atria) beat too quickly. Atrial flutter involves the atria...

Atrial fibrillation and atrial flutter are very fast electrical discharge patterns that make the atria (upper chambers of the heart) contract very rapidly, with some of the electrical impulses reaching the …

Apr 15, 2024 · Atrial fibrillation (AFib) is more common than atrial flutter, but both can lead to stroke. Learn the differences in causes, symptoms, and treatment.

Atrial flutter and atrial fibrillation (AFib) are two types of atrial tachycardia. Learn the differences and similarities of these two conditions, including their causes, symptoms, and treatment.

Dec 6, 2025 · While AFib and AFlutter are closely related and sometimes occur in the same patient, their underlying electrical mechanisms are fundamentally different. Understanding these distinctions, from …

Atrial flutter produces a more organized, regular rapid heart rhythm with predictable electrical patterns, while atrial fibrillation creates completely irregular, chaotic electrical signals. Symptoms can be …
