What is Atrial Fibrillation?

Atrial fibrillation, or AFib, is an abnormal heart rhythm. During AFib, the signal to start the heartbeat is disorganized, causing the upper chambers or atria of the heart to quiver or fibrillate. The contraction of the atria and the ventricles is no longer coordinated and the amount of blood pumped out to the body varies with each heartbeat. This can lead to blood pooling, increasing the risk of forming blood clots. These clots can then break off and lodge in an artery leading to the brain, which is why AFib significantly increases your risk for stroke.


Understanding Arrhythmia Risk Factors

AFib can occur from a range of conditions that change the heart’s electrical system. The risk of AFib increases as you age mostly because the risk for heart disease and other conditions that can cause AFib also increase as you get older.

AFib is more common in those who have:

Other Irregular Heartbeat Causes

AFib is also more likely to happen due to stress from an infection such as pneumonia or other illnesses, or right after surgery. Even stress from daily living, caffeine and alcohol may also induce an occurrence of an AFib attack or heart rhythm disturbances.


Diagnosing Atrial Fibrillation

With care available at locations across northeast Ohio, our physicians perform a thorough medical examination and diagnostic tests to identify heart rhythm irregularities. Tests for AFib include:

  • Electrocardiogram (ECG): A noninvasive recording of the electrical activity of your heart.
  • Holter monitor: A portable device that records a continuous record of the electrical activity of your heart for 24-48 hours. This would record heart rhythm abnormalities that occur intermittently and may be undetected on the ECG.
  • Event monitor: A portable device usually issued for 12-30 days to record arrhythmias that occur infrequently.

Atrial Fibrillation Treatment Options

Beyond providing leading medical, ablative and surgical treatments, University Hospitals’ experts also participate in clinical trials evaluating new strategies for treating AFib. Our team will work with you to create a specific treatment plan for your AFib targeting stroke prevention, heart rate control and ultimately means to restore normal sinus rhythm.
