(((((Freaked))))) - last year I had around a year of these palps all day every day. They totally freaked me out too!!! I barely had an hour without them. Then back last August they suddenly went. The following couple of months I had an odd few and then no more. I hope this gives you hope!
I did notice they had a lot to do with my digestion. I'd been through a spell of gastritis and went through a phase where food was repeating on me a bit (GERD). I researched this a lot and found out that bulemics (which I'm not) suffer a lot from palps too. They bring a lot of food back up all the time. My gastritis had healed, but I believe it had set off this problem. Maybe I even have a small hiatus hernia? Anyway all these things can irritate the vagus nerve that runs between the stomach and the heart and bring on these palps. Finally mine calmed down. I think the hormones in paeri make the vagus nerve sensitive to such disruption.
My cardio was useless denying the existence of peri for people under 50 or any possibility of the vagus nerve being responsible BUT my GP agreed with me this is very likely what happened. He told me that the problem with specialists is that they know an awful lot about a very little. They are very good when you have serious heart problems but know very little when it comes to innocent palps. They can diagnose them as such but that's about it. They know very little about other fields of medicine. He told me he sees an awful lot of people with gastro problems and palps (skipped beats).
I know how awful they are and my heart goes out to you - I spent my first year on this site battling them - I would say take magnesium, be kind to your digestion (try NoT to burp or regurg food if you possibly can as this was my problem with my gastritis and definitely aggravated the palps). I also had acupuncture which I believe helped me enormously. The other thing is to try not to panic as anxiety makes them worse too, but I do understand how hard this is not to. I had that too, peaking the year before the palps and still do have it to a point but the palps have gone despite it
