Atrial fibrillation, the most common type of arrhythmia, is an irregular, fast heartbeat that can cause poor blood flow from your heart to your body.

Atrial fibrillation (often called AFib) is caused by problems with the heart’s electrical system.

It can increase your risk of stroke and heart failure.

Atrial Fibrillation Symptoms

Atrial fibrillation often doesn’t produce clear symptoms. Symptoms may also start or stop suddenly. This is because atrial fibrillation may stop or start on its own.
Some symptoms you may notice include:

  • Sensations of feeling the heart beat (palpitations)
  • Shortness of breath
  • Weakness or difficulty exercising
  • Dizziness or fainting
  • Fatigue
  • Confusion

Arrhythmias can cause sudden cardiac arrest, which occurs when the heart’s electrical system stops working properly. You may experience the above symptoms before a sudden cardiac arrest.

However, when a sudden cardiac arrest happens, its symptoms are severe:

  • Sudden collapse
  • No pulse
  • No breathing
  • Loss of consciousness

Sudden cardiac arrest can result in sudden cardiac death within minutes without emergency treatment, such as CPR or defibrillation. If you or someone around you experiences these symptoms, call 911 immediately.
