Great question! Yes, it's actually possible to receive a shock from an ICD and have different experiences depending on the type of treatment delivered.
Here's what can happen:
- Overdrive pacing — This is a lower-energy pulse used to treat fast heart rhythms. It's generally much less noticeable and usually less painful than a full shock.
- Defibrillation shock — This is a stronger jolt to reset a dangerous heart rhythm. Most people do feel this, and it can be startling or uncomfortable.
- Backup pacing — Used for slow heart rhythms, this is typically very subtle and many people don't notice it at all. Whether passing out occurs depends on how quickly the ICD responds to the abnormal rhythm. If the dangerous rhythm is corrected fast enough, fainting may be avoided entirely.
It's worth noting that if fainting or sudden cardiac arrest has occurred, driving restrictions of up to six months may apply — so always check with a doctor about any activity limitations.
