Epilepsy/seizure?

I have a test on Epilepsy tomorrow for my health class however I missed a class and I need to know what a persons blood pressure would be after the seizure, also heart rate, pulse. oxygen level and how long would these stay "abnormal" before returning to normal. I know all the other symptoms such as convulsions, dizziness and ect… but i don't know what the "internal symptoms" would be. And would it be possible for everything to return to normal before paramedics arrive?

Thanks
Since it depends on the individual and type of seizure…Can anyone give me an example of past experiences if possible and what the symptoms were….
