Bella - I have the exact same thing happen to me. I'm pretty sure they are panic attacks. I read online somewhere that all of the symptoms (fast heartbeat, shortness of breath, etc.) happen because when you have a panic attack, your body is preparing to "fight or flight." Even though you're just sitting there reading a book, your mind convinces your body that you are in severe danger (think caveman times - being chased by a wild animal) so your heart beats fast to give you quick and fast energy. I totally sympathize with you - these things are so utterly scary it's ridiculous. I actually get them almost every time I have to take insulin. If it makes you feel any better, I've read that even though your heart starts racing, and even though you may feel like you're having a heart attack - you're not, and it's not harming your heart. I also lose concentration for a few minutes (it seems like I'm in a dream watching my own life - like I'm not actually in it). I've found that mine come much more often when I'm stressed. So maybe try to avoid stressors as much as possible for a few days and see if that helps. Also, I stopped drinking coffee when I started having these, and that helped out a bit. I'm sorry you're going through this - Good luck, and let me know if you come up with any solutions.
