Hey! Symptoms have improved a ton, as my neck and back have gotten stronger. The X-ray showed my neck was overly straight caused by a strained CT junction and weak muscles. I have been doing PT the past month to strengthen this area and my palpitations and other symptoms have improved tremendously. I also heard a hatial hernia can cause these types of symptoms, so if you get that after eating that likely is it. The vagus nerve can get irritated if stretched or compressed, that is what causes those weird palpitations, so fixing that will fix everything else most likely. I couldn’t believe how off and weak my neck was, it’s actually feeling better than it did before I hurt it in the first place! Good luck!

So interesting that you mention swallowing. Do you get palpitations after swallowing?
I have had palpitations since november. I first noticed them after I slept one night at a friends house on an extremely bad mattress and woke up with back pain. Since then I get them, about every 4-5 weeks for 2-3 days. In between I am always completely symptom free. Since then I also often wake up with back pain, but i never really connected those symptons until now.
I get the palpitations especially when swallowing, I swallow and 1-2 seconds later I feel my heart stumbling. Sometimes I even have several extra beats in a row, which really scare me. I have had a holter monitor twice so far. However, I never had any symptoms while wearing it, and it always came back normal. My heart echo also was normal.
