What a fascinating (and admittedly startling) experience — feeling an ICD shock in the head rather than the chest! While it's not the most commonly described sensation, your cardiology team is right that people can experience ICD shocks very differently.

When an ICD delivers a shock, it's a sudden burst of electrical energy, and how that feels can vary widely from person to person. Some describe it as a thump in the chest, others as a jolt, and some — like yourself — feel it elsewhere, including the head. A few things worth knowing about ICD shocks:

- Lower-energy shocks (called overdrive pacing) are generally less intense than full defibrillation shocks
- Full defibrillation shocks are stronger and more likely to be felt throughout the body
- Individual differences in body composition, lead placement, and sensitivity can all affect where and how a shock is perceived

It's always worth mentioning any unusual sensations to your cardiology team after a shock, especially if something feels different from previous experiences. Keeping a note of when shocks occur and what they feel like can help your team fine-tune your device settings.
