I think my girlfriend has epilepsy?

My girlfriend was sleeping and all of a sudden her body shakes & hands are like shaking a lot, & her breathing gets very heavy and she chokes to breathe like she stops breathing & then catches her breath. When she woke from having the shaking fit her eyes were just open like staring but not fully with it, after a few mins she came round and was saying her chest was hurting, her pulse was very fast and rapid. I'm very worried, could this be something serious?
