Atrial fibrillation and atrial flutter are types of arrhythmia. Both occur due to problems with the electrical signals in the upper chambers of the heart. And while they present with similar symptoms, they are not the same condition. Read on to learn what separates these abnormal heart rhythms.
Atrial fibrillation is more common than atrial flutter.
According to the American Heart Association, “at least 2.7 million Americans are living with AFib.” On the other hand, atrial flutter is more rare. The latter is usually seen in patients with some form of heart disease, or who have undergone cardiac surgery or an ablation.
The major difference between AFib and atrial flutter is the organization of the electrical signals in the pathways of the heart.
In AFib, the atria receive disorganized electrical impulses.This causes the atria to beat out of coordination with the heart’s ventricles, and leads to a rapid and irregular heartbeat.
In atrial flutter, the atria receives organized signals, but the signals are faster than normal. These rapid signals cause the atria to beat more frequently than the ventricles, and a pulse rate of about 150 bpm. On an EKG, atrial flutter will produce a distinctive “sawtooth” pattern
It is difficult to differentiate these two arrhythmias based on symptoms alone.
Both AFib and atrial flutter may cause rapid pulse, irregular pulse, tiredness, palpitations, shortness of breath, dizziness, chest pain and tightness, and even stroke. Atrial flutter symptoms tend to be less severe, may not always include an irregular pulse, and the risk of stroke is lower.
If you’ve noticed any symptoms in line with AFib, atrial flutter, or an otherwise abnormal heart beat, it’s important to see a cardiologist for a comprehensive evaluation.
