Abstract
An attempt of PCS was performed for the first time in Japan. Eighteen hundred twenty-six preschool and school children were examined and the result was compared with other studies (physician's auscultation and PCG). The time requirement for a single child is approximately 1.5 min. in primary school. It took long time in kindergarten. The heart murmur detection rate is high and the sensitivity is fairly good, although it is not so good as well-trained physician's heart murmur detection rate. PCS is not perfect, but is fairly good tool for screening. It can be used only by technician. PCS may be able to save the physician's time.
