recurrent Atrial Fibrillation

What is Atrial Fibrillation?

Atrial fibrillation (AF or A-fib) is an irregular and often rapid heart rate that can cause poor blood flow to the rest of the body. It's the most common type of arrhythmia, or heart rhythm problem. The atria are the upper chambers of the heart that allow blood to flow between the heart and lungs. During atrial fibrillation, the atria beat irregularly and too quickly, which can lead to blood clots, stroke, heart failure, and other complications.

Symptoms of Atrial Fibrillation

Atrial fibrillation may not cause noticeable symptoms. Symptoms of atrial fibrillation often include:

  • A racing or irregular heart rate
  • Fatigue
  • Shortness of breath
  • Chest pain
  • Lightheadedness or dizziness
  • Sweating or flushing
  • Heart palpitations

Risk Factors for Atrial Fibrillation

Risk factors for atrial fibrillation include:

  • Age: Atrial fibrillation is most common in people older than 65.
  • High blood pressure
  • Heart disease
  • Lung disease
  • Hypothyroidism
  • Sleep apnea
  • Diabetes
  • Excessive alcohol use
  • Excessive caffeine consumption

Complications of Atrial Fibrillation

Atrial fibrillation can cause several complications, including:

  • Blood clots
  • Stroke
  • Heart failure
  • Cardiac arrest
  • Atrial flutter
  • Abnormal heart rhythms
  • Arrhythmias

Treatments for Atrial Fibrillation

Treatment for atrial fibrillation depends on the severity of the condition. Treatment may include:

  • Medications to regulate heartbeat and prevent blood clots
  • Procedures to destroy small areas of abnormal tissue in the heart
  • Implantable cardioverter defibrillator to help regulate heart rate and rhythm
  • Surgery to correct structural abnormalities in the heart
  • Lifestyle modifications, such as quitting smoking and limiting caffeine and alcohol
