I have suffered from palpitations on and off since I can remember. Recently though when I get an attack I get a feeling in my throat that I could be sick and I also seem to want to cough all the time. Episodes are frightening and when I get them I don't want to go out until everything settles back to normal. I don't drink, don't smoke have tried just about everything to get rid of them. I've been seen by the cardiologists in the past and am booked to see another. I take beta blockers which don't seem to do anything and my GP has suggested I increase the dose as they have started waking me up during the night. I am working but struggle in case I get an episode of them whilst at work which I suppose makes me more anxious. Does anyone out there have similar symptoms?
