OK. Stroke is bleeding in the brain. Blood vessels there are more fragile than in extremities, or even other organs. Hyrdrostatic shock (from impact to the head) can tear them.
And if the guy did suffer a heart attack (a really major one to cause fatal brain damage) due to being tazed, he should have been treated in a hospital. Heart attack from being tazed though isn't likely unless the person is over 50. A 44 year old, maybe.
