The heartbeat is controlled by electrical impulses that begin in the atria, or upper chamber of your heart.; In AFib, these electrical impulses are erratic, causing a rapid and irregular heartbeat that affects the heart's ability to pump blood efficiently to the rest of the body.

Symptoms of AFib Include:

  • Irregular or rapid pulse or heartbeat
  • Dizziness, sensation of light-headedness
  • Sensation of your heart fluttering (palpitations)
  • Sensation of missed or extra heartbeat
  • Weakness
  • Fatigue
  • Shortness of breath

Some people may not experience symptoms while others may have noticeable symptoms.

Treatments for AFib

  • Antiarrhythmic medications
  • Electrical cardioversion or defibrillation
  • Automatic implantable defibrillator
  • Artificial pacemaker
  • Catheter ablation
  • Surgical intervention

If AFib or any arrhythmia is left untreated, it can lead to stroke or heart failure.
