What is Atrial Fibrillation?

Atrial Fibrillation (AFib) is an irregular and often rapid heart rhythm that can lead to blood clots, stroke, heart failure, and other heart-related complications. This condition occurs when the heart's two upper chambers (the atria) beat out of coordination with the two lower chambers (the ventricles).

Symptoms of Atrial Fibrillation May Include:

• Irregular or rapid heartbeat (palpitations)
• Shortness of breath
• Fatigue or weakness
• Dizziness or lightheadedness
• Chest pain
• Difficulty exercising

Facts About Atrial Fibrillation

• AFib is the most common type of heart arrhythmia, affecting millions of people worldwide.
• It significantly increases the risk of stroke, with AFib-related strokes tending to be more severe than other types.

Who is at Risk for Atrial Fibrillation?

Risk factors for atrial fibrillation may include:

• Genetics: A family history of AFib or other heart arrhythmias can increase your risk.
• Sex: AFib is more common in men, but women with AFib have a higher risk of stroke.
• Age: The likelihood of developing AFib increases with age, particularly in those over 65.
• Race or Ethnicity: Caucasians are more likely to develop AFib than other racial groups.
• Environment: Lifestyle factors such as alcohol consumption, stress, and sleep apnea can contribute to AFib.
• Other Risk Factors: High blood pressure, heart disease, obesity, and diabetes are major contributors to the development of AFib.

How Many Americans Have Atrial Fibrillation?

It is estimated that over 5 million Americans have atrial fibrillation, and this number is expected to rise as the population ages.

Diagnosis & Management

Atrial fibrillation is diagnosed through a physical exam, electrocardiogram (ECG), Holter monitor, or other advanced tests like an echocardiogram. Proper diagnosis is essential for effective management and to reduce the risk of stroke.

Treatment Options for Atrial Fibrillation

Medical and Pharmaceutical Treatments

• Medications: Anticoagulants, rate control medications, and rhythm control drugs are commonly prescribed to manage AFib.
• Procedures: Electrical cardioversion, catheter ablation, or surgical interventions like a maze procedure may be necessary for persistent cases.

Lifestyle Interventions

• Diet and Exercise: Maintaining a healthy diet and regular physical activity can help manage AFib.
• Reducing Alcohol and Caffeine: Limiting the intake of alcohol and caffeine can reduce AFib episodes.
• Stress Management: Techniques like yoga and meditation can help lower the frequency of AFib episodes.
