When I was 8, I started having heart palpitations. It kinda feels like you are having a strong hard heartbeat. And it kind of makes you feel funny for a split second. Kind of short of breath or something. I went to a specialist because they were concerned that it could be a clogged heart valve. But it wasnt, it was just an innocent heart murmur. I do have it rechecked every so often, just to make sure that nothing has changed. So far I have a healthy heart. I also get chest cramps sometimes when I take a deep breath. The doctor told me to stretch my upper body out until it goes away. I guess I am kind of a freak of nature.

But I have had them every so often for 20 years and will forever. If you are concerned about it, or have a history or heart problems in your family, I would get it checked out. That way you know.
