I am 23 years old, and have recently been into hospital a few times for tests on my heart and chest.
I have had various symptoms such as breathlessness, tight chest, palpitations and a numbness in my left arm.
I had a blood pressure test, a chest x-ray, blood test and an ECG, all came back fine. I was then diagnosed with Acid Reflux, but am still convinced it could be my heart. The only thing that came back was that I had a slightly slow heartbeat.
After I try to get any sort of exercise it seems to get worse, and after I eat meals. Also the last couple of days I have been having sleeping problems. Last night I went to bed, and my heart was pounding and I started to sweat, and couldnt get to sleep for about 40 minutes. The same sort of thing happened at about 5am the other morning, when I woke up with the sam sort of conditions.
Naturally I am very concerned. Are there any heart conditions that this could be, that may not show up on an ECG?
Thanks for your help!
