I have a question about Seizures?

I'm writing a story and in the story there is a flashback with a doctor. He (being a fictional character) is going to say a man had a seizure in front of a car and soon go into cardiac arrest. Now. If I have heard correctly, there are two kinds of seizures? One where you compulsivly shake and the other where you kind of p out, but stay in the same position. Like you are frozen. Is this correct? If so, is there a name for the second one? Thank you!
