Hello doctor , My kid is 2 yrs 8 months old . He is a normal and active child meeting all milestones . During his recent vaccination . Doctor suggested he heard some murmurs in heart beat and referred for echo test . We went for the same however kid was extremely cranky and test was not done properly. The doc who did the scan he wasn't able to do properly said he is not sure there might be a hole . We don't see any other symptoms n child is normal . Please advise if it needs urgent attention or we can wait for a few days
