What if I had external defibrillation, like with an AED (Automatic External Defibrillator)?

If an external defibrillator or AED must be used, it should be used. However, it may change the settings or damage your ICD. If external defibrillation or AED is used, the implanted device should be checked for proper settings afterward.  Consult your doctor if you ever get defibrillated externally.
