Baby heart murmur, grade 2, serious?

The severity of a grade 2 heart murmur in infants needs to be assessed in conjunction with the specific circumstances.

In general, normal heart murmurs in newborns and infants are around grade 2. If such murmurs occur between the second and third ribs on the left edge of the sternum or between the second and third ribs on the right edge of the sternum, they are called physiological murmurs. They are not serious and will gradually disappear with age. However, if grade 2 heart murs persist or worsen, they are mostly pathological murmurs and may be related to heart disease. Common heart diseases causing pathological murmur include ventricular septal defect, atrial septal defect, patent ductus arteriosus, etc., which are relatively serious. It is

recommended to pay attention to observation and seek medical attention as necessary for detailed examination and evaluation to determine whether treatment is needed.
