Hi I'm 16 and I'm having problems with my chest lately. Every now and then I feel like my heart is beating abnormally fast and it takes my breath away and I don't know what to do. Can awayone help me and tell me what this may be? Thank you :)

I would go to a doctor right away, as it may be symptoms of a congenital heart defect, or a heart murmur, or a number of other things.
