Atrial Fibrillation (AFib): Understanding the Irregular Heartbeat

What is Atrial Fibrillation (AFib)?

Atrial fibrillation, often called AFib, is a common heart rhythm disorder. In AFib, the heart beats in an irregular way. Usually, your heart pumps blood in a steady rhythm. However, with AFib, the upper chambers of the heart (called atria) beat out of sync with the lower chambers. As a result, blood may not flow as well as it should. This irregular heartbeat can lead to health problems, including stroke and heart failure. According to the CDC, millions of people worldwide live with AFib.

Common Symptoms of AFib

AFib symptoms can vary from person to person. Some people may not notice any signs. Others may feel symptoms often. For example, you might notice:

Heart palpitations (a fluttering or racing feeling in your chest)

Shortness of breath, especially during activity

Weakness or tiredness

Dizziness or feeling lightheaded

Chest pain or discomfort

Sometimes, symptoms come and go. But in other cases, they may last longer. If you feel any of these signs, it is important to talk to your doctor.

Causes and Risk Factors

Many things can cause AFib. Often, it is linked to changes in the heart’s structure. For instance, high blood pressure or heart disease can raise your risk. Other common causes and risk factors include:

Older age

Family history of AFib

Obesity

Diabetes

Sleep apnea

Heavy alcohol use

Thyroid problems

Sometimes, AFib can happen without a clear cause. Even so, knowing your risk factors can help you take steps to protect your heart.

How AFib is Diagnosed

Doctors use several tests to find out if you have AFib. First, your doctor will ask about your symptoms and health history. Next, they may listen to your heart. To confirm AFib, your doctor may order tests such as:

Electrocardiogram (ECG or EKG): This test records your heart’s electrical activity.

Holter monitor: You wear this device to track your heartbeat over one or two days.

Echocardiogram: This test uses sound waves to create pictures of your heart.

Blood tests: These can check for thyroid problems or other causes.

With these tests, your doctor can see if your heart rhythm is irregular and decide on the best treatment.

Treatment Options for AFib

Treating AFib helps lower your risk of stroke and other problems. Treatment depends on your symptoms, age, and health. Common AFib treatment options include:

Medications: These help control your heart rate or rhythm. Blood thinners may be used to prevent clots.

Electrical cardioversion: Doctors use a mild electric shock to restore a normal heartbeat.

Ablation: This procedure destroys small areas of heart tissue causing the irregular rhythm.

Pacemaker: In some cases, a small device is placed in your chest to help control your heartbeat.

Your doctor will explain which treatment is best for you. Sometimes, a mix of treatments works best.

Lifestyle Tips and Prevention

Healthy habits can help manage AFib and lower your risk. For example, you can:

Eat a heart-healthy diet with fruits, vegetables, and whole grains

Exercise regularly, but talk to your doctor first

Maintain a healthy weight

Limit alcohol and avoid smoking

Manage stress with relaxation techniques

Take your medications as prescribed

By making these changes, you can support your heart and feel better each day.
