A heartbeat is usually controlled by coordinated electrical signals that keep the heart pumping in a steady rhythm. In atrial fibrillation (AFib), these signals become disorganised, causing the upper chambers of the heart to beat irregularly. Some people notice a racing or fluttering heartbeat, while others may have few or no symptoms.
AFib deserves medical attention because an irregular rhythm can allow blood to pool inside the heart and increase the risk of blood clots and stroke. The American Heart Association reports that AFib is associated with an estimated fivefold increase in stroke risk.
At SGVP Holistic Hospital in Ahmedabad, patients with palpitations or irregular heartbeats can undergo cardiac evaluation with tests such as ECG and echocardiography to help diagnose AFib and guide treatment
In this article, we explain the symptoms, causes, types, diagnosis, and treatment options for atrial fibrillation, along with when cardiac evaluation may be necessary.
What is Atrial Fibrillation?
Atrial fibrillation is a heart rhythm disorder in which the heart’s upper chambers, called the atria, beat rapidly and irregularly. This prevents the atria from contracting in the organised pattern seen during a normal heartbeat.
Electrical signals normally begin at the heart’s natural pacemaker and travel through the chambers in a coordinated sequence. During AFib, multiple abnormal electrical signals interfere with this process.
As a result:
- The pulse may become irregular.
- The heartbeat may sometimes become unusually fast.
- The atria may not empty blood efficiently.
- Blood may remain within the atria and form clots in susceptible patients.
- The heart may become less efficient at pumping when the rhythm remains uncontrolled.
Not every irregular heartbeat represents AFib. An electrocardiogram is generally needed to confirm the rhythm and guide further assessment.
What Are the Types of Atrial Fibrillation?
The types of atrial fibrillation are mainly classified according to how long episodes last and whether the abnormal rhythm stops spontaneously. The pattern can also change over time, so continued follow-up may be necessary.
Common clinical patterns include:
- Paroxysmal AFib: Episodes begin and stop and may resolve without treatment.
- Persistent AFib: The abnormal rhythm continues and may require treatment to restore normal rhythm.
- Long-standing persistent AFib: AFib remains continuously present for an extended period.
- Permanent AFib: The patient and treating team decide not to pursue further attempts to restore sinus rhythm and instead focus on appropriate rate control and stroke prevention.
The classification helps cardiologists select an appropriate treatment strategy. It does not, by itself, determine how serious a patient’s condition is.
What Are the Symptoms of Atrial Fibrillation?
Atrial fibrillation symptoms may include palpitations, fatigue, breathlessness, dizziness or reduced exercise tolerance. Some people have no noticeable symptoms and discover AFib during an ECG or medical evaluation for another reason.
Possible symptoms include:
- A racing, pounding or fluttering heartbeat
- An irregular pulse
- Unusual tiredness or weakness
- Shortness of breath
- Dizziness or light-headedness
- Reduced ability to exercise
- Chest discomfort
- Fainting or near-fainting in some cases
Symptoms may occur intermittently or continue for longer periods. Their intensity also varies considerably between patients.
Having mild symptoms does not necessarily mean AFib can be ignored. Even people who do not feel the abnormal rhythm may still have an increased risk of stroke or other cardiovascular complications.
When Do AFib Symptoms Need Urgent Medical Attention?
AFib requires urgent assessment when an irregular heartbeat occurs with severe chest pain, marked breathlessness, fainting or possible stroke symptoms. These symptoms may indicate a cardiac or neurological emergency rather than an uncomplicated episode of palpitations.
Seek emergency medical care for:
- New or severe chest pain
- Severe difficulty breathing
- Loss of consciousness
- Sudden facial weakness
- Weakness or numbness affecting one side of the body
- Sudden difficulty speaking or understanding speech
- Severe unexplained dizziness with neurological symptoms
A person experiencing these symptoms should not wait for a routine cardiology appointment.
What Causes Atrial Fibrillation?
Atrial fibrillation causes commonly involve changes or stress affecting the heart’s electrical system, although a single identifiable cause is not always found. Heart disease, high blood pressure, and several non-cardiac conditions may contribute to its development.
Conditions associated with AFib include:
- Long-standing high blood pressure
- Coronary artery disease
- Previous heart attack
- Heart valve disorders
- Heart failure
- Cardiomyopathy
- Congenital heart conditions
- Thyroid disorders
- Sleep apnoea
- Obesity
- Diabetes
- Previous heart surgery
Alcohol consumption and tobacco use may also increase risk in some people. Age is another important factor, with AFib becoming more common as people get older.
Who is More Likely to Develop AFib?
AFib can occur in anyone, but the likelihood increases with age and certain cardiovascular or metabolic conditions. Having several risk factors together can further increase the chance of developing an abnormal rhythm.
Risk is higher among people with:
- Increasing age
- High blood pressure
- Existing heart disease
- Diabetes
- Obesity
- Sleep apnoea
- Previous heart surgery
- A history of smoking
- Significant alcohol exposure
- Certain thyroid conditions
Risk factors should be considered together rather than used for self-diagnosis. Palpitations can have several causes, and an ECG is needed to identify the actual rhythm.
How is Atrial Fibrillation Diagnosed?
Atrial fibrillation is usually confirmed using an electrocardiogram, or ECG, which records the heart’s electrical activity. Further investigations may be needed to determine how frequently AFib occurs and whether an underlying heart condition is contributing to it.
The evaluation may include:
- ECG: Confirms the abnormal rhythm when AFib is occurring during the recording.
- Ambulatory rhythm monitoring: Records heart rhythm for longer periods when symptoms are intermittent.
- Echocardiography: Examines heart chambers, pumping function and heart valves.
- Blood tests: May identify thyroid problems, electrolyte abnormalities or other contributing conditions.
- Additional cardiac testing: Selected patients may require stress testing or further cardiac imaging based on their symptoms and medical history.
SGVP Holistic Hospital’s cardiology services include ECG, 2D/4D echocardiography, strain and stress echocardiography, treadmill testing and electrophysiology services among the available cardiac investigations and procedures.
An accurate diagnosis also involves determining how AFib affects the individual patient. Cardiologists consider symptoms, episode duration, other heart disease and the person’s risk of blood clots before choosing treatment.
What Are the Treatment Options for Atrial Fibrillation?
Atrial fibrillation treatment aims to control the heart rate or rhythm, reduce symptoms and prevent complications such as stroke. The exact combination of treatments depends on the patient’s symptoms, AFib pattern, medical conditions and individual stroke risk.
| Treatment goal | Possible approach | Why it may be considered |
| Control heart rate | Rate-controlling medicines | Helps prevent persistently rapid heart rates |
| Restore normal rhythm | Antiarrhythmic medicines or cardioversion | May restore sinus rhythm in suitable patients |
| Maintain normal rhythm | Medicines or catheter ablation | May reduce recurrent symptomatic AFib |
| Reduce stroke risk | Anticoagulant medicines | Helps prevent blood clot-related stroke when indicated |
| Address contributing factors | Management of blood pressure, weight, sleep apnoea and other conditions | Supports overall AFib management |
1. Medicines for AFib
Medicines may be used to control heart rate, manage rhythm or reduce the risk of blood clots. These are different treatment objectives, which is why two people with AFib may receive very different medication plans.
Rate-control medicines may include beta blockers or selected calcium-channel blockers. Antiarrhythmic medicines may be considered when rhythm control is appropriate.
Anticoagulants, commonly referred to as blood thinners, are prescribed according to an individual’s stroke and bleeding risk. Not every patient with AFib automatically requires the same anticoagulant treatment.
2. Cardioversion
Cardioversion aims to restore a normal heart rhythm in selected patients with AFib. Electrical cardioversion delivers a controlled electrical shock to reset the rhythm, while medication may sometimes be used for pharmacological cardioversion.
Because AFib can allow blood clots to form inside the heart, doctors assess clot and stroke risk before cardioversion. Anticoagulant treatment or additional testing may therefore be required around the procedure.
3. Catheter Ablation
Catheter ablation may be considered when rhythm control is appropriate, particularly for patients with symptomatic or recurrent AFib. The procedure targets areas involved in producing or transmitting abnormal electrical signals.
During radiofrequency ablation, thin catheters are guided into the heart and controlled energy is delivered to selected tissue. The aim is to prevent abnormal electrical signals from repeatedly triggering AFib.
Ablation is not automatically required for every person with AFib. The decision depends on symptoms, previous treatment, AFib pattern, underlying heart disease, and the patient’s overall health.

How Can People With AFib Manage Their Heart Health?
People with AFib can support their treatment by controlling cardiovascular risk factors and following the medical plan recommended by their cardiologist. Lifestyle measures complement medical treatment but do not replace anticoagulation, rhythm treatment or other prescribed therapies.
Useful measures may include:
- Taking medicines exactly as prescribed
- Keeping blood pressure under control
- Managing diabetes where present
- Maintaining a healthy body weight
- Avoiding smoking
- Limiting alcohol according to medical advice
- Managing diagnosed sleep apnoea
- Staying physically active at an appropriate level
- Attending scheduled cardiology follow-ups
Exercise recommendations should reflect the person’s age, symptoms and overall heart health. Anyone who develops chest pain, marked breathlessness, faintness or worsening palpitations during activity should stop and seek medical advice.
Conclusion
Atrial fibrillation can cause palpitations, tiredness, breathlessness and dizziness, although some people experience no clear symptoms. Because AFib can increase the risk of blood clots and stroke, an irregular or persistently rapid heartbeat should be medically assessed.
Anyone with severe chest pain, breathlessness, fainting or symptoms suggesting a stroke requires urgent medical assessment rather than waiting for a routine consultation.
Frequently Asked Questions
Yes, atrial fibrillation can be serious because it increases the risk of blood clots, stroke and heart-related complications. However, the individual risk varies. Appropriate rate or rhythm management and stroke prevention can help reduce complications.
Some episodes of paroxysmal AFib may stop without treatment, while persistent forms may continue until treated. Even if the heartbeat returns to normal, medical assessment is advisable because recurrent AFib and stroke risk may still require management.
Many people with AFib continue normal daily activities when their heart rate, rhythm and cardiovascular risks are appropriately managed. Activity recommendations vary according to symptoms, underlying heart disease, treatment and general health, so individual guidance remains important.
No. Anticoagulant treatment is based on the person’s estimated risk of stroke and bleeding rather than the AFib diagnosis alone. A cardiologist considers factors such as age, previous stroke, hypertension, diabetes and other cardiovascular conditions.
Catheter ablation may be considered for selected people with symptomatic or recurrent AFib when rhythm control is appropriate. The decision depends on AFib type, previous treatments, symptoms, other heart conditions and the patient’s individual clinical assessment.
High blood pressure (hypertension) is the single biggest and most common long-term risk factor for developing atrial fibrillation. However, for acute, individual attacks (flare-ups) that people feel day-to-day, alcohol is the most frequently reported lifestyle trigger by patients, cited in roughly 35% of cases.
