My daughter is 5 years only and recently went for her annual physical and the doctor heard a mumur when she was lying down. She did not hear the murmur in any other position. This is the first time this murmur has been detected. She recommended that she go see a pediatric cardiologist to clear her before she begins competitive sports. My question is given the fact that the murmur was only heard while lying down doesn't this indicate that the murmur is most likely innocent? Do mumur's associated with a structural problem disappear when standing up? Her appointment is next week but we are nervous. Any help would be appreciated.
A murmur is the term that we use for a sound created by turbulence in the heart. That turbulence can be normal or abnormal. Abnormal means that there is a structural defect. Normal means that the heart is structurally normal. There are 6 innocent, or normal, murmurs. The most common innocent murmur is the Still's murmur, which typically shows up between ages 2 and 6 years, is heard while lying down, and goes away with upright position. It is classically a vibratory sound. It is usually louder with a cold or fever, and is typically gone by adolescence. Abnormal, or pathologic, murmurs are typically heard in all positions. Hopefully your daughter's murmur will be the former, and not the latter.
