Hi everyone. Firstly, Im 20 Male from the UK. I have had anxiety ever scince i could remember, i always thought there was something wrong with me. I developed a form of tachycardia about 2 and a half years ago, my heartrate would race for no reason ect. I went the doctors and they insisted i was fine and told me im more aware of my HR then most. I passed all the blood test and through a stetascope my HR was fine. 2 and a Half years on i still have tachycardia daily and other symptoms, of which are: - Slow HR upon standing, sometimes i feel like im gonna pass out but never have - Stomach Pains and Bad Wind - Anxiety and severe panic attaks - Dizzyness - Pain in my lower back - Tiredness - Chest Pain + The Usual Anxiety related stuff and more that i forgot about. When you get scared your HR should go fast, but mine goes slow then fast. When i stand up i feel like my HR goes : BUMBUM, BUMBUM, BUM..BUM, BUUM...,BUMBUM, BUMBUM, like its missing beats. I had an ECG and they said my left artrium was a bit muscular then should be but isnt harmful and many people live with it undetected. These symtoms really scare me, ive got a feeling if i had a tilt table test i would fail it. Its really horrible and for a 20 year old having to live like this day in day out it isnt nice, i cant do what normal people do cos im scared to death. Thanks in advanced for all your support and related storys.
