Cardioversion is a treatment that may be used to correct the abnormal heart rhythm, atrial fibrillation (AF).

  • Cardioversion may be used, either on its own or in addition to drug treatment for AF.
  • The procedure uses a controlled electric shock to you heart, from a machine called a defibrillator, to restore your normal heart rhythm.
  • This allows the conduction system of your heart to reset. It can be performed under a general anaesthetic or with sedation.
  • Cardioversion can be repeated if necessary.

Not everyone with AF will be benefit from cardioversion treatment. Your heart specialist will carefully consider whether this is a possible treatment option for you.
