Difference between Afib and Flutter

Difference between Afib and Flutter

There are a few different types of heart arrhythmia, and each one can be confusing to understand. Here we will specifically discuss the differences between afib and flutter heart arrhythmia. Although both conditions involve an irregular heartbeat, they are caused by different things and require different treatment plans. So what are the key differences between these two conditions? Let’s take a closer look.

What is Afib?

Afib, or atrial fibrillation, is a heart arrhythmia that occurs when the heart’s upper chambers (the atria) beat too quickly and irregularly. Afib can cause blood to pool in the atria and increase the risk of blood clots, which can lead to stroke. Afib can also cause heart failure and other heart problems. While Afib is a serious condition, it is often treatable with medication, lifestyle changes, and surgery.

Afib is relatively common, affecting approximately 3 million Americans. Afib can occur at any age, but it is more common in older adults. If you think you may be experiencing Afib, it is important to see a doctor as soon as possible. Early diagnosis and treatment can help reduce your risk of complications.

What is Flutter?

Flutter is a heart arrhythmia that occurs when the upper chambers of the heart (the atria) beat too fast. This causes the heart to quiver, or flutter, instead of beating in a steady rhythm. Flutter is usually not life-threatening, but it can be uncomfortable and may lead to more serious arrhythmias. Flutter is often caused by an underlying heart condition, such as heart disease or valvular heart disease.

It can also be caused by electrolyte imbalances, certain medications, or extreme stress. Treatment for flutter typically involves controlling the underlying cause and managing symptoms. In some cases, medication may be necessary to slow the heart rate or prevent future episodes of flutter.

Difference between Afib and Flutter

Afib and flutter are both considered heart arrhythmias, which means that they are abnormal heart rhythms. Afib is the most common type of heart arrhythmia, and it occurs when the heart’s upper chambers (the atria) beat irregularly. This can cause the heart to pump less effectively, and it can lead to fatigue, shortness of breath, and even stroke.

Flutter is a less common type of arrhythmia, and it occurs when the heart’s lower chambers (the ventricles) beat irregularly. This can also cause the heart to pump less effectively, but it is not as dangerous as afib. Both afib and flutter can be treated with medication or surgery, depending on the severity of the condition.


While afib and flutter heart arrhythmias may share some similarities, they are two distinctly different conditions. If you experience any of the symptoms associated with either condition, it is important to seek medical help right away.
