how dangerous is a heart murmur?!
Question:
Answers:
Not all heart murmurs are very dangerous. In fact, most aren't. I have one and I didn't even know I had one until I was in seventh grade. My parents were told when I was born, but it never affected me. The heart murmur is worst when you are born and gets less important as you get older. This is because as you grow, the heart murmur stays the same size, and thus becomes less significant compared to the size of your heart. A heart murmur is caused by one of your valves between your chambers of your heart not closing all the way and a little blood squeezing backward into the previous chamber when your heart compresses (beats). If you haven't notices it all your life, it's probably not dangerous.

very dangerous, i'd go to a doctor
it depends how serious and how long the murmurs last.
I had murmurs when i was a kid (like 8) and i went to the doctor and they said they'd watch it through ocassional checkups. I eventually grew out of it.
I would definitely go to the doctor right away but don't freak out if you don't know for sure how bad it is.
A heart mummur can cause your heart to start beating out of Arythem which in case can cause congestive heart failure or a heart attack. So if it is left untreated it is very life threatening. With treatment should be no problems.
A heart murmur is usually not a problem and is normally caused by a defective valve in the heart. An innocent heart murmer will not cause problems, and it's usually recommend that you have antiobotic treatments prior to dental work to avoid heart infection.
Some can be very dangerous, so it's imporant to let your doctor determine if further testing is needed.
