I apologize for the long winded post, but I have 17 years of experiences to cover. I've been experiencing frequent heart palpitations and fluttering since 1994. Every heart test I've had over the years has been normal (EKG, ECG, stress tests, event monitors/holters, etc) aside from small preliminary beats and such that my doctors have deemed "insignificant". Other symptoms have been frequent belching "attacks" (not always related to eating) which I had a Barium study done for years back. My recollection of that study is that they were searching for signs of ulcer (which they found a small intestinal ulcer but did not seem concerned about it). Other heart symptoms have been tachycardia (sometimes after certain meals), and bradycardia (typically when hungry). I also started having panic attacks during the night in 2003 (anxiety runs in my family), and ended up being put on metoprolol (beta-blocker - still taking today). The panic attacks stopped, but the heart symptoms continued. I tried learning to live with it. In summer of 2011, panic attacks came back (life has been more stressful over the last 18 months...graduated from college, started new career, father passed away, etc). This time I also experienced more frequent and intense headaches (feels like tension headaches), weakness in legs (sometimes arms), joint stiffness (shoulders and back, etc) and tingling on left side of face (mostly during headaches, but not always). I generally feel crappy all the time (mild nausea, light-headedness, dizziness, low energy, weakness, etc). After reading up on nearly every ailment that mimics these symptoms (to no avail), I have been lead to GERD, hiatal hernia, and the vagus nerve as possible culprits. I have always believed that I did not have a heart problem, but that something else was causing my symptoms. While trying to assemble the puzzle pieces, I think back to the first day I began having heart flutters/skipped beats. I had been mountain biking earlier that day, and I remember carrying my bike up a hill and slipping. In doing so, I remember feeling a pain (but being 17 years ago I don't recall exactly where). I remember it being in my torso (like my chest or my back) as if I twisted and pulled something. I'm now wondering if I suffered a hiatal hernia that day, and have never had it diagnosed.If anyone has any insight into this possibility, I'd be thrilled to hear any news that I may be on to discovering the source of my long suffering.
