  • Implantable cardiac devices can help manage problems with your heart rate or heart rhythm.
  • Your heart has an electrical system (conducting system) that regulates the heart rate.
  • Damage to this system can cause conditions where the heart is unable to beat regularly and effectively, including ‘sick sinus syndrome’ and ‘heart block’.
  • An artificial pacemaker works by supporting the heart's natural rhythm.
  • An artificial implantable cardioverter defibrillator (AICD) can recognise a dangerous heart rhythm and send messages to the heart to try and slow the rhythm and return it to normal.
  • If this doesn't work, the AICD can send an electric shock to jolt the heart out of its fibrillation.
