My son is 4 years old has no issues was told he has a mild heart murmur but recently he tells me he can feel his heart beat and when i feel it its racing wnat could it be?

Discuss an EKG 12 lead screening test with your physician. Most likely there is no cardiac issue, and the exact details of the murmur is important information. A benign flow murmur is a commonly found incidental finding. Watch for signs of shortness of breath and fatigue. A virtual consultation with Healthtap is available.

If I listen to a kid often enough I will hear a murmur at some point. "Mild" murmur is doctor code for they don't think it is a problem. If you are concerned schedule a visit with the kids doc and discuss the worries you have. It may be you both have anxiety over the label. It might be there is a real issue the doctor needs to explore.
