I have a history of anxiety and having arrhythmias every now and then, but they've never been detected by EKG, 24, or 48 hour Holter monitor. They drive me to the edge every time, making me think I'm dying. I don't know what to do. I'm not sure if they're actually caused by anxiety, because they've occurred in the middle of the night while I'm sleeping, jolting me awake, and they've happened when I've had no anxiety that I was aware of. I don't know how to deal with this. I hadn't had any in a few months until today when I was just sitting in the waiting room as my car was getting serviced. No anxiety to speak of. Just lurched my body forward. A skipped beat and sudden tachycardia. It happened again just now. On and off tachycardia for a couple minutes. My chest is always sore for about a half hour after this occurs, and it's really scary for me. Also, for some reason my knee jerk reaction is to throw my body up and start pacing around really quickly and breathing deeply. It's like I feel like if I don't get up, I'll *** out and die. Yes, as you can see, a primary fear and source of anxiety for me is death. But my biggest issue is feeling like I can't have this treated because no physician has seen it occur. Please give me some advice.
