Can blood pressure rise THIS high during a panic attack?

yes it can, because during an anxiety attack you "panic" you believe you are dying. It is like someone is standing with a gun to your head, of course your are going to freak, and your body is going to act accordingly. But there are alot of things that help, and alot that don't. don't drink alot of caffine, or smoke alot, and while people smoke to relax, it only hinders you during a panic attack. You whole bady goes haywire in response to your fear.
