Pediatrics/sinus bradycardia and heart murmur


I took my twelve year old for a sports physical and they discovered a murmur that was never heard before,so we went for an EKG and chest x-ray. Chest x-ray was normal but EKG showed sinus bradycardia. The doctor is saying it is normal for an athlete but his father has been hospitalized with slow heart rate several times and I am wondering if it is a condition that is hereditary? He goes to see a pediatric cardiologist on Wed. and they are going to do an echo-cardiogram. I am wonder what kind of condition he may have or what may be going on? any thoughts would be appreciated.

Hi, Marie,

Sinus brady is normal.  The echo should be reassuring and will probably tell you that your 12 year old athlete has a normal heart and any murmur heard is a functional one, or innocent murmur.  If no one has ever heard a murmur in his repeated exams, then the chance of this being anything significant is virtually zero.

Good luck, Dr. Olson

I would be happy to attempt to answer any questions about general pediatric topics, either medical issues or behavioral issues. This would include all the various questions one receives in a busy pediatric practice. I`m a board certified pediatrician in northern Michigan and have been in practice for over 15 years. I enjoy the teaching role I have in our practice and would enjoy the opportunity to help others with their pediatric problems.
