Whats an Innocent Murmur?
The most common type of heart murmur is called functional or innocent. This diagnosis means the murmur is produced by a normal, healthy heart. It can come and go throughout childhood. It usually goes away on its own as the child gets older and doesn’t pose any health threat. Kids with innocent heart murmurs don’t require a special diet, restriction of activities, or any other special treatment. They do not need to take a dose of antibiotic before going to the dentist. Those old enough to understand that they have a heart murmur should be reassured that they aren’t any different from other kids. In other words, an innocent murmur is the sound of normal blood moving through a normal heart in a normal way. Just as we can sometimes hear the sound of air moving in an air duct or water flowing through a plumbing pipe, we can often hear the sound of blood moving through the heart even if there is not a heart problem.
