Good morning doctor, My daughter is 7 yrs old and sometimes some third sound comes from her heart.. instead lub dub I can feel a mur mur sound .

A. If You can hear any kind of a sound that is doubtful for you and that’s coming out from the heart of chest of your child then better get a check with your doctor maybe this is the congestion that you are here so it’s better to clear your mind by getting it assessed by a doctor
