Atrial fibrillation (Afib) is a common heart condition characterized by an irregular and often rapid heart rhythm. Many people who are diagnosed with Afib first seek information because they are experiencing unusual sensations and want to understand what is happening. A frequent question for those concerned about their heart health is, “What Does Afib Feel Like?”. The experience of atrial fibrillation can vary significantly from person to person. Some individuals may experience pronounced and disruptive symptoms, while others might not notice any symptoms at all. Understanding the range of sensations associated with Afib is crucial for early detection and management.
Common Symptoms of Afib
When atrial fibrillation symptoms do appear, they can manifest in a variety of ways. Here are some of the most frequently reported sensations:
-
Irregular Heartbeat: This is a hallmark symptom of Afib. Instead of a regular, steady pulse, you may feel your heart beating erratically. It may feel like your heart is out of sync or skipping beats.
-
Heart Palpitations: Palpitations are described as the sensation of your heart pounding, racing, fluttering, or skipping a beat. These can be quite noticeable and even alarming. The feeling might arise suddenly and can last from a few seconds to several minutes.

-
Rapid Heartbeat (Tachycardia): In Afib, the heart often beats faster than normal. A heartbeat exceeding 100 beats per minute at rest is considered rapid and can be a symptom of atrial fibrillation.
-
Fatigue: Feeling unusually tired or lacking energy is another common complaint among individuals with Afib. This fatigue can be persistent and may not be relieved by rest.
-
Reduced Exercise Tolerance: You might find it harder to perform physical activities that you previously found easy. Activities like walking, climbing stairs, or even simple household tasks might become more challenging due to shortness of breath or fatigue.
-
Chest Discomfort: Some people with Afib experience chest pain or tightness. This can range from a mild ache to a more pronounced discomfort in the chest area.
-
Shortness of Breath (Dyspnea): Feeling breathless, even at rest or with minimal exertion, can occur during Afib episodes. This is because the heart’s inefficient pumping can lead to reduced blood flow to the lungs and the rest of the body.
-
Lightheadedness, Dizziness, or Fainting: Afib can sometimes cause a drop in blood pressure, leading to lightheadedness, dizziness, or even fainting spells. These symptoms should be taken seriously as they can indicate a more significant issue.
It’s important to note that some individuals with atrial fibrillation may be asymptomatic, meaning they experience no noticeable symptoms. In these cases, Afib may only be detected during a routine medical check-up or tests conducted for other health concerns.
Types of Afib and Symptom Variation
The way Afib feels can also depend on the type of atrial fibrillation a person has:
-
Paroxysmal Atrial Fibrillation: Symptoms in this type of Afib come and go. Episodes start and stop on their own, usually within hours or days. Individuals with paroxysmal Afib might experience intermittent palpitations or other symptoms that resolve spontaneously.
-
Persistent Atrial Fibrillation: In persistent Afib, the irregular heart rhythm does not stop on its own and requires medical intervention, such as medication or cardioversion, to restore a normal rhythm. Symptoms are likely to be more sustained compared to paroxysmal Afib.
-
Permanent Atrial Fibrillation: This is when atrial fibrillation is ongoing and cannot be converted back to a normal rhythm with treatment. In permanent Afib, individuals live with the condition long-term and symptoms may be consistently present, although their intensity can still fluctuate.
When to Seek Medical Advice
Understanding when to seek medical help is crucial if you suspect you might be experiencing Afib symptoms.
Non-Urgent Advice: See a Doctor If:
- You suspect you are experiencing symptoms of atrial fibrillation.
- You are having heart palpitations that are recurring or worsening.
- You have been diagnosed with Afib, and your current treatment is not effectively managing your symptoms.
Immediate Action Required: Call Emergency Services If:
If you are currently experiencing a fast or irregular heartbeat accompanied by any of the following serious symptoms, it is vital to seek immediate medical attention. Call emergency services immediately if you have:
- Chest pain
- Shortness of breath
- Sweating
- Nausea or vomiting
- Fainting, dizziness, or falls
- Severe headache
- Weakness or numbness on one side of the face or body
- Blurred vision or loss of sight
- Confusion or difficulty speaking
Do not drive yourself to the emergency room if you are experiencing these symptoms. Call for emergency medical assistance so you can receive prompt and appropriate care.
Diagnosis and Tests for Afib
If a healthcare provider suspects atrial fibrillation, they will typically refer you to a cardiologist, a heart specialist. Diagnosis usually involves:
-
Medical History and Physical Exam: The doctor will ask about your symptoms and medical history, and will check your heart rate and rhythm.
-
Electrocardiogram (ECG): This is a primary diagnostic tool for Afib. An ECG records the electrical activity of your heart and can detect irregular rhythms.
-
Echocardiogram (Echo): An echocardiogram is an ultrasound of the heart. It helps to assess the structure and function of your heart and rule out other potential causes of symptoms.
-
Chest X-ray: A chest X-ray can provide information about the size and shape of your heart and lungs.
-
Blood Tests: Blood tests may be conducted to check for underlying conditions that could be contributing to Afib, such as thyroid problems or electrolyte imbalances.
Managing Afib and Improving Your Well-being
While there is currently no cure for atrial fibrillation, effective treatments are available to manage symptoms and reduce the risk of complications like stroke. Treatment strategies may include:
-
Medications: Medications are commonly prescribed to control heart rate, rhythm, and prevent blood clots. These can include rate-controlling drugs, rhythm-controlling drugs, and anticoagulants.
-
Catheter Ablation: This procedure involves using heat or cold energy to destroy small areas of heart tissue that are causing the irregular electrical signals.
-
Electrical Cardioversion: Cardioversion is a procedure where an electrical shock is delivered to the chest to reset the heart to a normal rhythm.
-
Pacemaker or Implantable Cardioverter Defibrillator (ICD): In some cases, a pacemaker or ICD may be implanted to regulate heart rhythm, especially if Afib is associated with a slow heart rate or risk of sudden cardiac arrest.

In addition to medical treatments, lifestyle modifications can play a significant role in managing Afib symptoms and improving overall well-being:
- Avoid Triggers: Identify and avoid potential triggers for Afib, such as caffeine, alcohol, spicy foods, stress, dehydration, and lack of sleep.
- Maintain a Healthy Weight: Being overweight or obese can increase the risk of Afib and worsen symptoms.
- Balanced Diet: Eating a heart-healthy diet low in saturated and trans fats, cholesterol, and sodium is beneficial.
- Regular Exercise: Engage in regular moderate-intensity exercise, aiming for at least 150 minutes per week. However, avoid excessive or strenuous exercise which might trigger Afib in some individuals.
- Quit Smoking: Smoking is detrimental to heart health and can worsen Afib.
- Limit Alcohol Intake: Excessive alcohol consumption is a known trigger for Afib.
Living with atrial fibrillation requires ongoing management and communication with your healthcare team. By understanding what Afib feels like, recognizing your symptoms, and adhering to recommended treatments and lifestyle adjustments, you can effectively manage this condition and maintain a good quality of life.
