Afib or anxiety

Is there any way of knowing if I have Atrial Fibrillation or just anxiety? I have had stomach pain, like burning acid, felt hot, felt that "falling" feeling in my throat that is followed by two fast heartbeats.. like "tap...tap...tap..TAPTAP...tap.. tap" and when the "taptap" happens i get the feeling.. as well as chest pain and weird left arm feelings. I feel shaky and fidgety, sometimes i feel like its hard to breathe.. and I have headaches.. 

I have had the holter for 24h and ekg but nothing was found. 

Im very afraid since my friend died from heart failure a year ago, he was the same age as me. 18.. he was gone in a second. I still cannot believe it.

Im afraid i have the same thing. I have had similar feelings when I was 11. I had ultrasound back then and it was all ok.. i dont know yall.. what would you do in my place? Thank you so so so much

emma,

   I am not a doctor, but it sounds like it is anxiety. I am suffering from the same exact thing right now, but my doctor believes it is from me tapering off of Celexa.

   My heart goes just like yours........tap, tap, tap, tap, taptap, tap, tap, tap, I actually went to the emergency room last Sunday and they did an ekg, drew blood and did a chest x-ray and all came back normal. The emergency room doctor also believes it from me tapering off of the Celexa too harshly.

   Try to relax (I know that can be hard to do) and think about seeing your doctor to discuss possible anxiety problems.

I have just about everything you described, from the heartbeat to the throat feeling. Almost like someone's hand is wrapped around the base of my throat! I also have the shaky, fidgety feeling. Accompanied with random weakness and tiredness. I get tingles in my arms and even my face! Sounds like the delights of anxiety to me...

Try to hang in there and tell yourself that the symptoms you are feeling are nothing more than anxiety. That's what I try to do. I tell myself that I've experienced these symptoms before and they didn't kill me, so it has to be the anxiety.

Stay positive!
