What is a heart murmur, and how is it usually diagnosed and/or treated?
The Pediatrician Answers:
A heart murmur is the sound made by blood flow in the heart. Some murmurs in children are normal; doctors just hear the normal blood flow due to the thin chest wall in a child. Other murmurs are due to turbulence from a cardiac (heart) malformation or other cardiac problem.
Murmurs are usually heard on the stethoscope exam and then the cause can be determined by an ultrasound/ECHOcardiogram. Normal murmurs need no treatment. Murmurs caused by cardiac malformations may require surgical correction of the malformation.
