AFib Care Network 

The AFib Care Network aims to teach patients about atrial fibrillation. One of our primary goals is to get you involved in your care and help you learn how to manage your atrial fibrillation. We also will work with other members of your care team to develop treatment strategies in order to give you the best chance at long-term success.  Patients seen at an AFib Transitions of Care location receive short-term care and an individualized treatment plan in partnership with your primary care provider. Our AFib Integrated Care option is available if you are in need of ongoing specialty care for atrial fibrillation.  Talk to your provider if you are interested in participating in our AFib Care Network. 

About Atrial Fibrillation

What is atrial fibrillation (AF, A-fib, AFib)?

Atrial fibrillation is an irregular heart rhythm in which the top chambers of the heart (atria) fibrillate (quiver or twitch quickly) instead of fully contracting. This causes the bottom chambers of the heart to beat irregularly. A normal heart rate is around 60 to 100 beats per minute. When someone is in A-fib, the atria may beat as often as 300 times per minute. Atrial fibrillation is the most common heart rhythm disorder in the world. Some people with A-fib feel no symptoms at all, while others are aware as soon as an episode happens. 

Common symptoms of atrial fibrillation include:

  • Fatigue or lack of energy
  • Dizziness, lightheadedness, or fainting 
  • Chest pain, pressure, or tightness
  • Shortness of breath
  • Heart pounding/racing
  • Increased urination
  • Trouble completing daily activities

What are the dangers of atrial fibrillation?

  • Stroke: Because the top chambers of the heart do not fully squeeze when in atrial fibrillation, blood can pool and allow clots to form. Blood clots from the heart can travel to the brain and cause stroke.
  • Heart failure (weakening of the heart muscle): very fast heart rates over time can cause the heart muscle to weaken
  • Lower quality of life: Many patients with atrial fibrillation experience fatigue, lower energy, shortness of breath, or other symptoms that interfere with daily life

Ask your Doctor

Patients with atrial fibrillation are at increased risk for stroke and developing heart failure. Therefore, it is important for patients to see a provider for proper care and treatment. Ask your doctor today about your options. 


Treatment of atrial fibrillation aims to make people feel better and improve quality of life. Treatment focuses on the following:

Preventing AFib

Anyone can develop atrial fibrillation, although there are common risk factors. These include high blood pressure, sleep apnea, thyroid disease, obesity, coronary artery disease, heart failure, heart valve disease, excessive alcohol or stimulant use, prior open-heart surgery, chronic lung disease, diabetes, and age >60 years. An important part of treatment for AFib is controlling these risk factors as much as possible. 

Preventing stroke

Blood can pool in the atria during AFib, which can allow a clot to form. If a blood clot dislodges from the atria, it can cause a stroke. Patients with atrial fibrillation are almost always prescribed a blood thinner medication such as warfarin (Coumadin), dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis), or edoxaban (Savaysa.)

Patients who are at risk for stroke but unable to take a blood thinner may benefit from a Watchman™ left atrial appendage closure device. The left atrial appendage (LAA) is a small pouch in the left atrium of the heart and is the source of most stroke-causing blood clots. The device works as a plug to close the LAA, which prevents the clots from escaping the heart and travelling to the brain and cause a stroke.

Keeping the heart rate from going too fast

If left untreated, AFib can cause a fast, irregular pulse for long periods of time. This can cause the heart muscle to weaken leading to heart failure. Because of the potential for weakening of the heart muscle, it is important to keep the heart from beating too fast when in AFib. 

Medications are used to slow down the heart rate. Examples of types of medications that slow down the heart rate are beta-blockers (metoprolol, atenolol, carvedilol), calcium channel blockers (diltiazem, verapamil), or digoxin.

Keeping the heart in normal rhythm

Patients who have symptoms and feel poorly when in atrial fibrillation may need more aggressive treatment to put them back into normal rhythm and keep them in normal rhythm. This can be done with medications, cardioversion (external shock to the heart), or catheter ablation (radiofrequency lesions made on the inside of the heart to destroy AF triggers).

    How to handle an AFib Episode

    One of the biggest questions is what to do during an AFib episode. 

    When to manage AFib at home

    If you are feeling okay and it is your typical AFib episode, it is okay to wait it out at home and or go about your normal day if you feel up to it. You can try some relaxation exercises (deep breathing, imagining a peaceful place). Make notes about how long the episode lasted and how you felt to share with your provider at your next visit. 

    When to see or call your provider

    • If symptoms get worse or you start feeling worse
    • AFib lasts longer than 24 hours
    • AFib episodes become more frequent
    • To get an EKG to confirm that what you are feeling is AFib
    • Routine follow-up

    When to call 911 or go to the Emergency Room

    • Signs of stroke (sudden weakness, numbness, trouble seeing or speaking)
    • Passing out/nearly passing out
    • Severe lightheadedness
    • Chest pain
    • Trouble breathing
    • Feeling weak, cold sweats, or clamminess
    • Medication side-effects (bleeding, overdose)

      Last Quarterly Meeting Presentation


      Based on pilot data, we believe that a model of care delivery which increases access to AF specialty clinics with an easy transition from multiple points of entry (emergency department (ED), urgent care and primary care clinics) can reduce unnecessary hospitalizations and improve quality of care. Increasing specialty care access, particularly in regions serving a large vulnerable patient population, helps to reduce disparities in care. Further research efforts are under way.
