Atrial Fibrillation

What is atrial fibrillation?

Atrial fibrillation, commonly known as AFib, is a common and progressive disease, with no cure. But, with early and proper treatment, can be managed so that you can live a healthier, better quality life. AFib is a disorganized "quivering" of the upper chambers of the heart and is the most common type of abnormal heart rhythm. AFib alters how blood flows within the heart and increases the risk of developing blood clots that can lead to a heart attack or stroke. If you have AFib, you may feel short of breath, weak, tired or dizzy. You may even experience palpitations.

The condition is a growing health issue in the U.S. that affects approximately 3 - 6 million individuals each year. According to the American Heart Association, individuals with AFib are four to five times more likely to have a stroke and, if left untreated, can double the risk of heart-related deaths. The good news is that treatment options have increased and evolved to provide higher efficacy and lower risks. Early intervention leads to more positive outcomes. Do not wait to see your doctor if you think you may have atrial fibrillation.

Long-term or frequent AFib should not be ignored. Regular checkups and ongoing management give you the best chance of effectively managing your symptoms and reducing your risk for having a stroke or heart attack.

Signs and symptoms of AFib

Symptoms of atrial fibrillation can include:

  • Fatigue
  • Shortness of breath
  • Palpitations – a sensation of your heart racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest
  • Weakness
  • Reduced ability to exercise
  • Lightheadedness
  • Dizziness
  • Confusion
  • Chest pain
Risk factors of AFib

Certain factors may increase your risk of developing atrial fibrillation.

These include:

  • Age-related “wear and tear” on the heart
  • High blood pressure
  • Heart attack
  • Coronary artery disease
  • Abnormal heart valves
  • Heart defects you’re born with (congenital)
  • An overactive thyroid gland or other metabolic imbalance
  • Exposure to stimulants, such as medications, caffeine, or tobacco
  • Sick sinus syndrome — improper functioning of the heart’s natural pacemaker
  • Lung diseases
  • Previous heart surgery
  • Viral infections
  • Stress due to pneumonia, surgery or other illnesses
  • Sleep apnea
  • Diabetes
  • Chronic kidney disease
  • Alcohol consumption
  • Obesity
  • Family history
AFib treatments

When detected early, some people may control their symptoms and reduce their risk for heart disease simply by improving lifestyle habits, such as:

  • Stop smoking
  • Adopt a healthy low-fat, low-salt diet
  • Avoid alcohol
  • Minimize caffeine
  • Maintain healthy blood sugar levels
  • Exercise regularly to achieve a healthy weight
  • Manage stress

If treatment is needed, your physician may refer you to the AFib Clinic at Parkview Heart Institute where the care team will focus on managing your heart rate and rhythm. The team will discuss which therapies will be most appropriate for you.

Medications

  • Rate control
  • Rhythm control
  • Anticoagulation (blood thinner)

Procedures

  • Cardioversion (Electrical or chemical “reset” of the heart rhythm)
  • Ablation (minimally invasive procedure to block an irregular rhythm)
  • Pacemaker implant
  • Left atrial appendage occlusion
    • Surgical removal of the appendage 
    • Watchman device closes the appendage

In some cases, where long-term anticoagulation therapy (blood thinner) is not ideal, a procedure called left atrial appendage occlusion (LAAO) may be an option. In this minimally invasive procedure, a small screen device is placed in the heart to close the opening of a naturally occurring pocket, thus eliminating the space where blood clots most commonly occur.

Long-term or frequent AFib should not be ignored. Regular checkups by your primary care physician give you the best chance of effectively managing your symptoms.

All patients referred to the AFib Clinic will be evaluated and managed by a board-certified electrophysiologist. Treatment options include medications, cardioversion, implantable cardiac devices, ablation therapies and left atrial appendage closure therapy.
