What is the Difference Between Atrial Fibrillation and Atrial Flutter?

Atrial fibrillation (AFib) and atrial flutter are both types of arrhythmias, which are abnormal heart rhythms. They share similar causes, risk factors, symptoms, and treatments but have some differences as well. Here are the main differences between atrial fibrillation and atrial flutter:

1. Electrical impulses: In atrial flutter, the electrical impulses are organized, while in AFib, the electrical impulses are chaotic.
2. Frequency: AFib is more common than atrial flutter.
3. Treatment success: Ablation therapy is more successful in people with atrial flutter.
4. ECG patterns: In atrial flutter, there is a "sawtooth" pattern on an ECG, while in AFib, the ECG test shows an irregular ventricular rate.
5. Symptom severity: The symptoms of atrial flutter tend to be less severe than the symptoms of AFib.

Both AFib and atrial flutter can lead to an increased risk of developing a blood clot in the heart and consequently increase a patient's risk of stroke. However, many patients have both conditions, as one rhythm can transition into another. Treatments for both conditions may include medications, ablation therapy, and lifestyle changes, depending on the severity of the condition and the patient's overall health.

Comparative Table: Atrial Fibrillation vs Atrial Flutter

Atrial fibrillation (AFib) and atrial flutter are two types of atrial tachycardia, which are abnormal heart rhythms resulting from issues with the electrical signals and pathways in the heart. Here is a table comparing the differences between the two conditions:

Both AFib and atrial flutter can cause strokes, but the risk is higher for AFib. While atrial flutter may revert spontaneously to sinus rhythm in some patients, treatment is often required to manage atrial fibrillation.
