Heart sound screening was performed on elementary school children in three San Mateo County communities, using the Phonocardioscan, a portable analog-digital computer. Although these communities differed significantly in socio-economic backgrounds, the incidence of previously known and unknown heart disease was not dissimilar. However, there was an unusual difference in community reaction to the heart sound study, with the families in the middle class area exhibiting more anxiety than those in the high and low income communities.
在圣马特奥县的三个社区,使用便携式模拟 - 数字计算机心音扫描仪对小学生进行了心音筛查。尽管这些社区的社会经济背景差异很大,但已知和未知心脏病的发病率并无不同。然而,社区对心音研究的反应存在异常差异,中产阶级社区的家庭比高收入和低收入社区的家庭表现出更多焦虑。
