Atrial flutter is a type of abnormal heart rhythm (arrhythmia) that occurs when the atria (upper chambers of the heart) beat too fast, typically between 250-350 beats per minute. This rapid atrial activity leads to an irregular or rapid heart rate, as the ventricles (lower chambers) may not be able to keep up efficiently.

Unlike atrial fibrillation, atrial flutter has a more organised electrical pattern, often forming a characteristic "sawtooth" wave on an ECG. While it may not always cause symptoms, untreated atrial flutter can increase the risk of complications like stroke and heart failure, requiring medical intervention. Let us understand the symptoms, causes, and treatment options in detail.

Recognising the Symptoms of Atrial Flutter

If you have atrial flutter, you may experience the following symptoms, which can range from mild to severe:

Rapid heartbeat (palpitations) causes a sensation of a fast or pounding heart.
Persistent episodes of dizziness or lightheadedness.
Shortness of breath or having trouble breathing, especially during exertion.
Reduced exercise tolerance or inability to perform physical activities without exhaustion.
Fatigue, unusual tiredness or lack of energy.
Fainting (syncope) in severe cases, or even loss of consciousness.
Chest discomfort, often mild to moderate chest pain or pressure.
Swelling in legs or feet due to fluid buildup, particularly in long-term cases.

Understanding the Causes of Atrial Flutter

Atrial flutter can be triggered by various factors, including underlying heart conditions and lifestyle influences:

High Blood Pressure puts increased strain on the heart and can trigger irregular rhythms.
Diabetes & obesity can increase the risk of heart rhythm disorders.
Previous heart surgery including scarring can affect heart electrical signals.
Excessive alcohol or caffeine contains stimulants which can interfere with heart function.
Heart Disease like coronary artery disease, heart failure, or valve disorders.
Medications and certain drugs, including stimulants and heart medications, may trigger arrhythmias.
Electrolyte imbalance such as low levels of potassium, magnesium, or calcium can affect heart signals.
Lung diseases such as COPD, pulmonary embolism, or sleep apnea may contribute.
Thyroid disorders such as overactive thyroid (hyperthyroidism) can disrupt heart rhythm.
Ageing can increase the risk of atrial flutter due to natural heart changes.

Treatment Options for Atrial Flutter

Below are the treatment options that follows post atrial flutter diagnosis:

1. Medications

Antiarrhythmic drugs: Help restore and maintain normal heart rhythm.
Rate control medications: Beta-blockers and calcium channel blockers slow the heart rate.
Blood thinners (Anticoagulants): They are used to reduce the risk of stroke by preventing blood clots.

2. Cardioversion

Electrical Cardioversion: A controlled electric shock restores normal rhythm (gold standard treatment).
Pharmacological Cardioversion: Medications used to reset the heart rhythm.

3. Catheter Ablation

A minimally invasive procedure that destroys abnormal electrical pathways in the heart, offering a long-term cure.

4. Lifestyle Modifications

Avoid stimulants like alcohol, caffeine, and nicotine.
Managing stress through relaxation techniques.
Following a heart-healthy diet and regular exercise.

5. Treating Underlying Conditions

Managing high blood pressure, thyroid disorders, and heart disease to reduce recurrence.

6. Regular Monitoring & Follow-ups

Routine ECGs and medical check-ups to track heart health and prevent complications.

Did You Know?

Atrial flutter can cause the heart to beat up to 300 times per minute, but the body regulates it at a lower rate!
Atrial Flutter is often curable with catheter ablation, a minimally invasive procedure that stops the abnormal heart signals.

Myths and Facts

Myth 1: Only older adults get atrial flutter.
Fact: While more common with age, younger individuals with heart conditions or lifestyle risks can also develop it.

Myth 2: Atrial Flutter is the same as Atrial Fibrillation.
Fact: No. Atrial Flutter and Atrial Fibrillation are slightly different. While both are arrhythmias, atrial flutter has a more organised rhythm, making it easier to treat.

Myth 3: Atrial flutter isn’t serious and doesn’t need treatment.
Fact: If untreated, it can lead to complications like stroke or heart failure, making timely treatment essential.

Conclusion

Atrial flutter is a manageable heart rhythm disorder that, if treated promptly, does not have to interfere with a healthy life. With effective treatment options such as medications, cardioversion, and catheter ablation, most individuals can restore and maintain a normal heart rhythm. Lifestyle modifications and managing underlying conditions further reduce the risk of recurrence and are significantly helpful in atrial flutter management.
