What is a baby heart murmur?

Children with heart murmur can be physiological or pathological. Children with heart murmur should understand the intensity, location and nature of the murmur. Some children can show physiological murmur, and physiological murmur is mostly systolic murmur. Some children should consider congenital heart disease, such as atrial septal defect and ventricular septal defect. Congenital heart disease is the cause of heart murmur in children. Children with heart murmur should be routinely examined by cardiac color Doppler ultrasound, which can generally determine the cause of heart murmur.
