In order to get valuable information for efficient application of PCG and ausculation to mass examination, discussion was made of the characteristics of heart murmurs and sounds of normal children and of congenital heart diseases and acquired valvular heart diseases which are more prevalent among the young. In the first chapter, the heart murmurs of children, especially functional murmurs are examined by both auscultation and PCG and the role of them in mass examination is evaluated. In the second chapter, the use of PCG for mass examination is described especially for re-examination. In the third chapter discussion is made how to differentiate functional heart murmurs from pathologic ones, whose differentiation is difficult by auscultation. In the forth chapter physiologic diastolic murmurs which have not been generally taken into consideration are discussed.
