pss i also have the burping when mine are in full force, and the air in chest / heartburn
i feel for you , i to have thoses darn things, since i was 12 now am 51 and they are still with me. i have lived a scared life with them up till about 15 years ago and i got mad, i was tired of them ruining my life so i said STOP and decided to go on about my day with them in toll. yes they still scare me and yes they get on my nerves but i have a great support husband there to help me get throught the bad times. i have had over 3000 a day thats not many to most, but its more than enought for me, and i have the really fast heart beat like yours. i do take a bete blocker for that and it has helped so much through the years. try not to let them scare you to where like me i didnt want to leave my house. its hard to belive that they wont kill you / wear your heart out/ d damage to your heart, but guess what they wont. i have had many many years of them some good years some bad, but everytime i have a echo my heart is perfect, so i know they do not hurt your heart, they are just a pest. please go see a cardio if you have not and get the test for peace of mind. always here to talk. take care . ps eat less caffine , read labels lots in food.
If you haven't consulted with a cardiologist, I would certainly encourage you to do so. You say a "consultant" viewed the results, but you do not indicate what type of consultant this is. I would certainly want some tests to rule out anyting that needed attention. The fluttering can be a benign arryhthmia, and the chest discomfort can be indigestion. But heart attack symptoms can mimic indigestion. it's your statement "I just don't feel right in the chest are" concerns me. Take care, Ally
