Perhaps they would, but I would guess that you would still get scared when hearing the warning instead of the shock it self.

For example if you would get stabbed 15 seconds after hearing a beep I think you would develop pavlovian like response to the beep itself.

Counterpoint: a warning may not avert the fear but still be beneficial in cases where the person needs to prepare themselves to avoid a sudden fall/etc.

Could see it very useful if you're driving. Might even save other peoples lives in the case of a crash.

If I had a disease like that - I would not want to drive at all.

Depends on the jurisdiction, but in most places it is unlawful to drive in the 6-18 months following implant or a shock from an ICD.

What if it had the user press a button to trigger the shock? Would it help them prepare for it?
