What Is Atrial Flutter?
Atrial flutter is a type of abnormal heart rhythm in which the upper chambers of the heart (atria) beat very rapidly but in a more organized pattern than atrial fibrillation. Although the rhythm is more regular than AFib, atrial flutter can still reduce the heart’s efficiency and increase the risk of blood clots, stroke, and heart failure.
Atrial flutter may occur on its own or alongside atrial fibrillation.
Why Atrial Flutter Matters
Without treatment, atrial flutter can increase the risk of stroke and other cardiovascular complications. Early diagnosis and appropriate treatment help restore a healthier heart rhythm and improve blood flow.
Common Symptoms
- Rapid heartbeat
- Heart palpitations
- Shortness of breath
- Fatigue
- Dizziness
- Chest discomfort
- Reduced exercise tolerance
Common Causes and Risk Factors
- Coronary artery disease
- High blood pressure
- Heart valve disease
- Heart surgery
- Heart failure
- Chronic lung disease
- Hyperthyroidism
- Excessive alcohol consumption
How Is Atrial Flutter Diagnosed?
Diagnosis typically includes an electrocardiogram (ECG), Holter monitor, event monitor, echocardiogram, blood tests, and other cardiac evaluations to identify the abnormal rhythm and its underlying cause.
How Is Atrial Flutter Treated?
Treatment may include medications to control heart rate or rhythm, blood thinners to reduce stroke risk, electrical cardioversion, catheter ablation, or treatment of underlying heart conditions.
How Home Care Can Help
Home care professionals support individuals by encouraging medication adherence, monitoring heart rate and symptoms, promoting heart-healthy habits, assisting with daily activities, and recognizing warning signs that require prompt medical evaluation.
Home Care Tip
Keep all scheduled follow-up appointments with your cardiologist, even if your symptoms improve, to ensure your heart rhythm remains well controlled.
Frequently Asked Questions About Atrial Flutter
Is atrial flutter the same as atrial fibrillation?
No. Both are abnormal heart rhythms, but atrial flutter has a more organized electrical pattern. The two conditions may occur together.
Can atrial flutter be cured?
Many people experience long-term success with catheter ablation, although some may continue to require medications or additional treatment.
Can home care help someone with atrial flutter?
Yes. Home care professionals assist with medication management, symptom monitoring, heart-healthy lifestyle support, and recovery following treatment.
When to Seek Emergency Medical Care
Seek immediate medical attention if you develop chest pain, severe shortness of breath, fainting, stroke symptoms, or a rapid heartbeat associated with severe dizziness or weakness.
