Of course the best way to determine whether heart symptoms are psychological is to get tested. I was checked twice not too long ago, but can't afford more thorough tests. I've had panic disorder for 23 years! I should be the expert. Indeed months, even years, at a time, I've convinced myself that it's all psychological, that I'm actually qualified to help other people, only to find myself having symptoms again. Naturally, I know the root cause is psychological, but I fear that my own power of suggesion---negative suggestion that is----might provoke a heart attack. It would seem silly to someone who doesn't have the same problem--just don't worry about it and you'll be fine, but the only way not to worry is by being able to assure yourself that there's nothing to worry about. I can understand if I've been suggesting it to myself that I might get panic attacks, but when I haven't even been thinking about them and they come anyway, that's scary. I think to myself, it can't be the power of suggestion because I haven't even been thinking about it. Okay, so it's not suggestion, but rather anxiety and a conditioned response. Well, that works for me...for a while. A few months ago, out of the blue, at a time when my heart was the last thing on my mind, I wasn't stressed, I got this well....sort of rush from my chest up to my throat and then a sensation of a lump, similar to the symptoms I get when I used to get extrasystoles, a skipped heart beat in other words. However on these more recent bouts, I don't feel so much the lump in my throat, but rather more like a queasy, extremely unpleasant, light bubble going up to my throat. It happens in a flash and it's gone. I immediately feel dizzy and light headed, and in less than two seconds, it's gone. I don't get it again for weeks or months at a time. Afterward, I feel at least some pressure in my chest and slight pain in my left arm, and light-headedness.
