I've tried describing it to my doctor in the past and she once diagnosed it as bronchitis. She measured the strength of my breath and easily diagnosed it as that and prescribed me to an asthma inhaler... this was after meeting my doctor for the first time after 10 minutes. I didn't want to use the inhaler so I've never have... but I have it just in case, then, I went again and she tried to do an EKG? The heart rate meter thingy... and I had done it like a month before and it was fine, so I told her that and she put it away. I don't think it's my heart anyway.... I still have a problem with it, but I don't want to keep bugging my doctor about it.
