Atrial Flutter

What is Atrial flutter?

What is Atrial flutter?

Atrial flutter is an abnormal irregular heartbeat or a cardiac arrhythmia that happens when the heart's upper chambers (the atria) beat too fast, resulting in a rapid and irregular pulse. Abnormalities cause an atrial flutter in the heart's electrical conduction system that can be diagnosed using an electrocardiogram (ECG). Atrial flutter Symptoms are palpitations, shortness of breath, and chest pain, which can be managed through different treatment options, such as medication, catheter ablation, or electrical cardioversion.

What are the Different Types of Atrial Flutter?

Several types of atrial flutter include:

  • Typical atrial flutter: This is localized to the right atrium and is the most common type of atrial flutter, accounting for about 90% of cases. The specific pattern of electrical activity in the heart classifies typical atrial flutter.

  • Atypical atrial flutter: This kind of atrial flutter does not have the characteristic pattern seen in typical atrial flutter and can be challenging to diagnose and treat.

  • Macroreentrant atrial tachycardia: This type of atrial flutter involves multiple circuits of electrical activity in the heart that can be more difficult to treat. It may require a combination of medication and catheter ablation. Atrial fibrillation treatment options may impact the type of atrial flutter a person experiences.


Atrial flutter symptoms vary from person to person. However, common symptoms of atrial flutter include:

  • Palpitations or heart racing
  • Shortness of breath
  • Rapid and irregular heartbeat
  • Chest pain or discomfort
  • Dizziness or light-headedness
  • Fatigue or weakness
  • Anxiety 

Atrial flutter can lead to severe complications if left untreated, such as stroke,
heart failure, or blood clots. Therefore, its essential to seek medical attention
if you experience any of these Atrial flutter symptoms.


Abnormalities in the heart's electrical conduction system cause an atrial flutter, which is associated with the control of timing and coordination of the heart's contractions. This condition happens when electrical signals in the heart's upper chambers (the atria) become disorganized and spread rapidly, resulting in a fast and often irregular heartbeat.
The atrial flutter cause is not always clear, but it is usually associated with underlying heart conditions, such as:

  •  Coronary artery disease
  • Heart failure
  • Hypertension (high blood pressure)
  • Cardiomyopathy (disease of the heart muscle)
  • Heart valve disease
  • Pulmonary embolism (blood clot in the lungs)
  • Chronic obstructive pulmonary disease
  • Thyroid disease
    In some cases, atrial flutter may also happen without an underlying heart
    condition, known as lone atrial flutter.

Risk Factors

Atrial flutter risk factors include: 

  • Age: Atrial flutter is more common in more aged adults, particularly
    those who are over the age of 60.
  • Underlying heart conditions: Problems such as coronary artery disease,
    heart failure, or valve disease can cause a higher risk of developing
    atrial flutter.
  • Family history: atrial fibrillation or other heartbeat disorders can develop
    due to family history.
  • Alcohol and drug use: People addicted to alcohol and drugs are more
    porn to developing atrial flutter.
  • Obesity: Being overweight and Obesity are commonly responsible for
    increasing the risk of developing atrial flutter.
  • Sleep apnoea: Sleep apnoea is a condition when a person breathes irregularly during sleep, which can be a reason for developing the risk of developing atrial flutter.
  • Chronic obstructive pulmonary disease (COPD): COPD is a condition where the lungs include chronic bronchitis and emphysema, which can cause atrial flutter.
  • Recent surgery or illness: Recent surgery can increase the risk of developing atrial flutter.

It is crucial to recognize and control these Atrial flutter symptoms and causing factors to help a person from preventing the chance of developing atrial flutter.

How to Prevent Atrial Flutter Fibrillation?

Atrial flutter can be prevented by addressing the underlying risk factors
contributing to its development. Here are some ways to reduce the risk of this

  • Maintain a healthy weight: Overweight or obese can increase the risk of developing atrial flutter. Maintaining a healthy weight through a balanced diet and regular exercise help to prevent atrial flutter fibrillation.
  • Manage underlying medical conditions: Conditions such as hypertension, diabetes, and sleep apnoea, can reduce the risk of developing atrial flutter.
  • Limit alcohol and drug use: Avoiding the consumption of alcohol and harmful drug can help control atrial flutter.
  • Avoid triggers: Excess stress, caffeine intake, and tobacco usage can cause a trigger that needs to be prevented from helping control atrial flutter.
  • Take medications as prescribed: medications, such as blood thinners and anti-arrhythmic drugs, may be prescribed to prevent atrial flutter fibrillation, so its essential to take these medications as specified by your healthcare provider.
  • Get regular check-ups: Regular check-ups with your doctor can help determine and manage any underlying medical conditions that may increase the risk of developing atrial flutter.

While it may not be possible to prevent atrial flutter, taking these steps
completely can help decrease the risk of developing this illness.


Atrial fibrillation diagnoses include physical examination, medical history,
and diagnostic tests. Here are the standard techniques used to diagnose atrial

  • Physical examination: The doctor will perform a physical exam to check for any symptoms of atrial flutters. Irregular heartbeat or rapid pulse are some common examinations.
  • Electrocardiogram (ECG): An ECG is a test that records the heart's electrical activity. Abnormal heart rhythms, including atrial flutter, can be easily diagnosed through his test.
  • Holter monitor: Atrial fibrillation diagnosis also includes a Holter monitor, a portable ECG device used to record heart rhythms for 24-48 hours. It can detect irregular or periodic episodes of atrial flutter that may not be possible during a regular ECG.
  • Event recorder: An event recorder is a device worn for several weeks or
    months to record heart rhythms when symptoms appear. It can detect atrial flutter causes and other heart rhythm abnormalities.
  • Echocardiogram: It uses ultrasound waves to produce images of the heart. It can detect structural abnormalities or damage to the heart contributing to atrial flutter condition.
  •  Electrophysiology study (EPS): An EPS is a technical test that involves
    inserting a catheter into a blood vessel in the groin and threading it to the heart. This test can map the heart's electrical activity and identify the
    location of the atrial flutter. Further testing may be needed after diagnosing this condition to identify any underlying medical conditions contributing to the state.


Based on the characteristics of the heart rhythm, Atrial flutter can be divided
into four stages: 

  • Initiation: In this stage, the atrial rhythm is normal, but a single ectopic
    heartbeat or a premature atrial contraction (PAC) triggers an episode of
    atrial flutter.
  • Maintenance: During this stage, the fast and regular atrial rhythm is maintained due to a reentrant circuit in the atria. This reentrant circuit causes the electrical signals to travel in a circular pattern around the atria, resulting in the characteristic sawtooth pattern on an ECG.
  • Termination: The termination of atrial flutter can happen as an outcome of treatment or spontaneously. In some cases, the atrial flutter can spontaneously convert to a normal sinus rhythm, while in others, treatment such as medication or electrical cardioversion may be needed.
  • Recurrence: Atrial flutter can recur again after an episode, especially in people with underlying medical conditions contributing to its development. Recurrence can be more often if the underlying medical condition is not controlled. These stages of atrial fibrillation can guide Doctors in managing the condition.

Treatment and Management for Atrial Flutter

Atrial Fibrillation treatment and management condition depend on the severity and frequency of symptoms, the underlying cause, and other factors. Here are the standard methods for how to prevent atrial fibrillation:


  • Medications

    Medications: Anti-arrhythmic medications such as beta-blockers,
    calcium channel blockers, and sodium channel blockers can help slow
    down the heart rate and help maintain a normal heart rhythm. Blood-
    thinning medications, such as aspirin or warfarin, may also reduce the
    risk of blood clots and stroke.

  • Electrical cardioversion

    Electrical cardioversion: This process involves the delivery of a
    controlled electric shock to the heart to revive a normal heart rhythm. It
    may be used in cases where medication is not working or in
    emergencies when the heart rate is dangerously high.

  • Catheter ablation

    Catheter ablation: This method applies the use of a catheter inserted through a blood vessel in the groin and directed to the heart to destroy the area of the heart tissue responsible for the abnormal electrical signals that cause atrial flutter.

  • Lifestyle changes

    Lifestyle changes: Certain changes in Lifestyle, avoiding smoking, reducing the intake of alcohol or caffeine, and maintaining a healthy weight, can help reduce the frequency and severity of atrial flutter episodes.

  • Managing underlying medical conditions

    Managing underlying medical conditions: Treating and managing underlying medical conditions, such as high blood pressure, diabetes, and sleep apnoea, can help control or reduce the event of atrial flutter.

  • Pacemaker

    Pacemaker: In some circumstances, a pacemaker may be implanted to control the heart rate and rhythm.
