How fast is your heart when you play video games

A person's heartbeat will vary between videogames in which the player is playing.

For example:

If a gamer were playing F.E.A.R. on the X-Box 360, they might get scared because that is what the game is intended to do, so the heart will beat a little faster because of the shock.

If a gamer were playing Petz: Dogz, they might get bored and their heart will beat slower because of lack of excitement.
