Atrial flutter and atrial fibrillation are both abnormal heart rhythms. They affect the upper chambers of the heart. Knowing the difference between them is key for good care and treatment.Learn what AFib flutter is, how it differs from atrial fibrillation, and the treatments available for both.
At Liv Hospital, we focus on clear answers and safe treatments for these conditions. Atrial flutter, or AFib flutter, is a rapid but regular heartbeat. On the other hand, atrial fibrillation has an irregular and often fast heartbeat.
It’s important to understand the difference between these conditions to get the right care. We’ll explore their definitions, symptoms, causes, diagnosis, and treatment options in this article.

It’s important to know about heart rhythm disorders to diagnose and treat them. Conditions like atrial fibrillation and atrial flutter happen when the heart’s electrical system gets disrupted. This leads to irregular heartbeats or arrhythmias.
The heart’s electrical system is complex and controls the heartbeat. It usually beats between 60 to 100 times per minute. This system makes sure the heart pumps blood efficiently by contracting and relaxing in sync.
The electrical impulses that control the heartbeat start in the sinoatrial (SA) node, the heart’s natural pacemaker. These impulses then go through the atrioventricular (AV) node and the bundle of His. They reach the ventricles, making them contract.
Cardiac arrhythmias can be divided based on where they start and how they affect the heart. Atrial fibrillation (AFib) and atrial flutter are two types. They are fast and irregular heart rhythms that start in the atria.
In AFib, the heart rate can be very irregular, often over 100 beats per minute. It can even go up to 250 to 350 beats per minute. Atrial flutter, though, has a more regular but fast heart rate.
| Condition | Typical Heart Rate | Rhythm Characteristics |
| Normal Heart Rhythm | 60-100 bpm | Regular |
| Atrial Fibrillation | Often >100 bpm, can be highly irregular | Irregularly irregular |
| Atrial Flutter | Typically 250-350 bpm, but can be slower with treatment | Regular or slightly irregular |
Knowing these differences is key for the right diagnosis and treatment. We’ll look closer at atrial fibrillation and atrial flutter in the next sections. We’ll cover their causes, symptoms, and treatment options.

Atrial flutter, also known as AFib flutter, is a heart condition. It makes the heart beat fast but regularly. The heart’s upper chambers, or atria, beat 250 to 350 times a minute.
This fast heartbeat can cause symptoms like palpitations, shortness of breath, and fatigue.
Atrial flutter happens because of an abnormal electrical circuit in the heart. This circuit makes the atria beat fast and regularly, unlike the normal, coordinated rhythm. The mechanism is a re-entrant circuit where the electrical impulse goes in a loop.
This loop causes the atria to contract very quickly.
There are different types of atrial flutter, based on the circuit’s location and direction. Typical atrial flutter is the most common. It involves a circuit around the tricuspid valve. Atypical atrial flutter has circuits in other parts of the atria.
Knowing the different types of atrial flutter is key to finding the right treatment. We’ll look at treatment options in later sections.
Atrial fibrillation and atrial flutter are both abnormal heart rhythms. They differ in their electrical activity and heart rate. Knowing these differences helps in diagnosing and treating them effectively.
The main difference between AFib and AFib Flutter is in their electrical patterns. AFib has chaotic, irregular electrical activity in the atria. This causes the heart to quiver instead of contracting normally.
Atrial flutter, on the other hand, has a more organized, rapid electrical circuit. It usually happens in one area of the heart. This leads to a fast but regular heart rhythm.
In atrial flutter, the electrical activity follows a predictable pattern. It looks like a “sawtooth” or “flutter” wave on an EKG. This is very different from the chaotic activity seen in AFib.
AFib and AFib Flutter also differ in heart rate. AFib leads to an irregularly irregular heart rhythm. The heartbeat can change a lot from one beat to the next.
Atrial flutter, on the other hand, has a regular but fast heart rate. The heart rate in atrial flutter can be controlled or not, depending on several factors.
It’s common for patients to have both AFib and atrial flutter. Sometimes, atrial flutter can turn into AFib, or vice versa. This makes diagnosing and treating them more complex.
Understanding the differences between atrial fibrillation and atrial flutter is key. It helps healthcare providers create better treatment plans. By recognizing each condition’s unique features, we can improve patient care and outcomes.
It’s key for patients to spot atrial flutter signs early. This condition can affect daily life and health greatly.
People with atrial flutter may feel different things. Here are some common symptoms:
Medical Expert, a cardiologist, says, “Seeing a doctor is vital if you have these symptoms. They can help figure out what’s wrong and how to fix it.”
Get help right away if you notice:
Getting help early can make a big difference for atrial flutter patients. Pay attention to your body and don’t delay in getting medical help.
“Quick medical check-ups are key to catching atrial flutter early. This helps start the right treatment and avoid serious problems.”
Knowing what causes atrial flutter is key to managing it. It can come from heart issues, other health problems, and lifestyle choices.
Heart problems can raise the chance of getting atrial flutter. These include:
As Medical Expert, a cardiologist, once said,
“Heart conditions can greatly increase the risk of atrial flutter. It’s important to manage these conditions well.”
Other health issues can also lead to atrial flutter. These include:
Lifestyle choices can also increase the risk of atrial flutter. These include:
By knowing these causes and risks, we can manage and maybe even prevent atrial flutter. It’s important to work with doctors to identify and reduce these risks.
The diagnosis of atrial flutter mainly relies on electrocardiogram (EKG) findings. An EKG is a non-invasive test that records the heart’s electrical activity. It provides key information about heart rhythm disorders.
During an EKG, electrodes are placed on the chest to capture the heart’s electrical signals. These signals are then displayed as a tracing on the EKG paper or screen. In atrial flutter, the EKG shows a characteristic pattern that helps diagnose the condition.
One of the hallmark signs of atrial flutter on an EKG is the “sawtooth” or “flutter” wave pattern. This pattern is due to the rapid, regular atrial contractions typical of atrial flutter. The “sawtooth” appearance is usually most visible in the inferior leads (II, III, and aVF) on the EKG.
While an EKG is key for diagnosing atrial flutter, more tests may be needed. These tests help understand the underlying cause and guide treatment decisions. Some of these tests include:
Accurate diagnosis is key for an effective treatment plan. By combining EKG findings with other diagnostic tests, healthcare providers can better understand the nature of the atrial flutter. They can then tailor the treatment to the individual’s needs.

There are many ways to treat atrial flutter. These methods aim to control the heart rate, restore normal rhythm, and prevent blood clots. The right treatment depends on several factors. These include how long the atrial flutter lasts, any heart conditions, and the patient’s overall health.
Medicines are key in managing atrial flutter. They help control the heart rate and prevent blood clots. We use different medicines, like beta-blockers, calcium channel blockers, and anti-arrhythmic drugs, to achieve these goals.
Beta-blockers and calcium channel blockers help control the heart rate. This improves symptoms and quality of life. Anti-arrhythmic medicines, such as ibutilide and amiodarone, help convert atrial flutter to a normal rhythm or keep it normal after treatment.
Catheter ablation is a very effective treatment for atrial flutter. It’s best for those who are symptomatic or haven’t responded to medicines. This procedure uses catheters to destroy the abnormal electrical pathway in the heart.
This procedure has a high success rate, often curing atrial flutter. We do this in an electrophysiology lab under fluoroscopic guidance.
Other treatments for atrial flutter include cardioversion. This involves using electrical shocks to restore a normal heart rhythm.
Cardioversion is often used with blood thinners to prevent stroke. The choice between cardioversion and catheter ablation depends on several factors. These include the patient’s preferences, how long the atrial flutter has lasted, and any underlying heart disease.
| Treatment Option | Description | Benefits |
| Medication | Use of beta-blockers, calcium channel blockers, and anti-arrhythmic drugs to control heart rate and rhythm. | Improves symptoms, reduces risk of complications. |
| Catheter Ablation | Minimally invasive procedure to destroy abnormal electrical pathways. | High success rate, potentially curative. |
| Cardioversion | Electrical shock to restore normal heart rhythm. | Quick restoration of sinus rhythm, often used with anticoagulation. |
It’s important to know the complications of atrial flutter to manage it well. Atrial flutter can cause serious health problems if not treated right. It can affect many parts of a person’s health.
Atrial flutter increases the risk of stroke. Blood clots form in the heart and can travel to the brain. This makes stroke risk much higher for those with atrial flutter.
Patients with atrial flutter should talk to their doctor about their stroke risk. They need to find the best treatment to lower this risk.
Atrial flutter can also lead to heart failure. This is when the heart can’t pump enough blood. Symptoms include fatigue, shortness of breath, and swelling in the legs.
Managing atrial flutter well is key to avoiding these problems. It’s not just about medicine. Changing your lifestyle can also help your heart.
By understanding and tackling atrial flutter complications, we can lower the risk of serious health issues. This improves patient outcomes.
To prevent and manage atrial flutter, it’s important to make changes in daily habits. Ongoing monitoring and emotional support are also key. These steps help manage the condition and lower the risk of complications.
Making lifestyle changes can greatly help manage atrial flutter. Key modifications include:
These changes help manage atrial flutter and improve heart health. It’s essential to work with a healthcare provider to develop a personalized plan.
Regular monitoring is vital for managing atrial flutter effectively. This includes:
Monitoring helps in early detection of any changes or complications, allowing for timely intervention.
Living with atrial flutter can have emotional and psychological impacts. Seeking support is a critical part of managing the condition. This can involve:
By addressing the emotional and psychological aspects of atrial flutter, individuals can improve their overall quality of life.
In conclusion, preventing and managing atrial flutter requires a multifaceted approach. This includes lifestyle modifications, regular monitoring, and emotional support. By adopting these strategies, individuals can better manage their condition and improve their overall health.
Atrial flutter and atrial fibrillation are serious heart rhythm disorders. They need quick medical help. We’ve looked at how they differ, including their unique electrical patterns and heart rates.
Knowing how atrial flutter works is key for treatment. Its “sawtooth” pattern on an EKG is a big clue. We’ve talked about treatments like medicines and catheter ablation.
Managing atrial flutter and atrial fibrillation is more than just medicine. It also means making lifestyle changes and keeping an eye on your health. Spotting symptoms early can prevent serious problems like stroke and heart failure.
We stress the need for a full approach to treating these conditions. This includes using the latest medical techniques and supportive care. This way, we can help people with these conditions get better.
Atrial flutter is a heart rhythm problem. It makes the heart beat too fast, usually between 240-340 beats per minute. This happens in the heart’s upper chambers.
Atrial flutter has a regular rhythm, unlike atrial fibrillation. Atrial fibrillation has a chaotic rhythm.
Symptoms include palpitations, shortness of breath, and dizziness. Some people don’t show symptoms at all.
It can be caused by heart problems like coronary artery disease. It can also be caused by non-heart issues like thyroid disorders or sleep apnea.
Doctors use an electrocardiogram (EKG) to diagnose it. This shows a “sawtooth” pattern. They might also use Holter monitoring or echocardiography.
Treatments include medications and catheter ablation. Other options include cardioversion.
You can’t prevent it completely. But managing heart conditions and staying healthy can help.
Complications include stroke and heart failure. Untreated atrial flutter can also lower your quality of life.
Manage it by making lifestyle changes and monitoring your heart. Emotional support is also important.
They are related conditions. People with one may get the other. They can happen together or separately.
Catheter ablation is a procedure. It destroys the bad electrical pathways in the heart. This treats atrial flutter.
