Just noticed that he hasn't been diagnosed, in my opinion experience they are quite benign (I think many people have them and don't get diagnosed). There have been threads on here before, it's also common to grow out of them by adulthood.
Here is some info to allay any worries you have (from netdoctor)
What are anoxic seizures?
A reflex anoxic seizure is a type of fit triggered by a temporary cutting off of the supply of blood to the brain.
It is NOT a form of epilepsy, and is different from breath-holding attacks.
A reflex anoxic seizure can be induced by any unexpected stimuli such as pain, fear or fright, or even by a very hot or cold bath.
The trigger factor causes the heart to stop or slow down dramatically, which in turn reduces the flow of blood to the brain.
The child goes limp, falls down and becomes very pale. The body may stiffen and there may be jerking movements of the arms and legs.
After a short while the blood flow to the brain is restored and the child rapidly returns to normal although they may sleep for some time afterwards.
Reflex anoxic seizures probably occur in about 8 out of every 1000 preschool children. They are most common between the ages of six months and two years but they can also occur in teenagers and adults.
Although parents often say their child looks as if they have died during an attack, I have never heard of the condition causing death.
Often no treatment is required, but some studies have suggested that the drug atropine is effective in reducing the frequency of the attacks.
Thankfully, reflex anoxic seizures usually get less frequent and eventually stop during childhood. Occasionally the attacks persist into early adult life.
