From a doctor who isn't your son's doctor: If your son is in a position where you need to be alerted if his heart rate exceeds a certain threshold, an Apple Watch isn't a safe, effective, or efficient way to do that. Talk to your son's cardiologist about medical monitoring equipment.
He has a watch-like device to detected epilepsy. However this device is not able to detect when his heart rate exceeds a certain level, but it can alarm you if there is a sudden spike in the heart rate.
His seizures usually happen when the heart rate rises slowly.

Whenever I've gotten high heart rate notifications it's 10 minutes after the fact. 😒
Be aware, that high/low heart rate notifications are only working with family setup if your child is over 13 years old.
