I'm not an expert or anything but my cousin has anxiety attacks ever so often. Usually it's a quicken heartbeat, shakiness, and cold sweats or hot flashes. Not everyone experiences it the same. There's a good website called http://www.anxietyinfo.com that has information on symptoms and such. Click the links and such to find out more. You may want to try searching for "Panic Attacks" on webmd because they may have it listed as that and I'm almost sure that they're the same thing. I also suggest looking at http://www.apa.org/pubinfo/panic.html which has a list of symptoms for a panic attack.

While it doesn't give the symptoms persay it does give you alot of information on anxiety attacks and possible causes for it. Go to http://www.emedicine.com/emerg/topic35.htm and scroll down and look around. Useful information on one or two typical drugs prescribed to treat anxiety attacks as well.

You may just wish to search the internet and see what you can dig up. Talk to your family doctor about it if you think you might be having them or someone you know is having them as they'd be the best people to diagnois them and be able to help. I am not a doctor and I am only giving you a few sites I know of that contain information on the subject but before you or anyone else takes any type of drug or self-diagnoises...please consult a doctor.
