In atrial fibrillation, a variety of electrical impulses happen all at one time inside your atria, which in turn causes extremely fast and disorganized contractions. What this means is your atria can’t pump bloodstream effectively to your ventricles.

Due to the disorganized electrical impulses that come from your atria, your ventricles may also contract very rapidly and irregularly. Consequently, it normally won’t pump bloodstream as effectively for your body. (2)

  • Cardiac arrest
  • Heart surgery
  • Hereditary heart defects
  • Other health problems can also increase the chance of developing afib, including: (1,3)
  • Chronic kidney disease
  • Diabetes
  • Hyperthyroidism (overactive thyroid)
  • Lung illnesses
  • Weight problems

  • Anti snoring
  • Venous thromboembolism (bloodstream clot)

Infections
