心音图对老年人的心脏方面的诊断和鉴别诊断,以及心脏病的血液动力学和对疾病病程的观察和病理生理等方面的研究,有一定价值。心音图随着医学科学的发展,近几年来国外已渐被广讯应用于临床医学。国内有些研究单位及临床医院也逐渐开展。但是至今尚未见到老年人正常心音图标准(正常数值)资料。因此,作者为了了解老年人的心音图正常值及异常程度,而选择了200名老年人,选择的标准是,多数老年人历来未体检过,无自觉症状,一般能照常参加脑力和体力劳动者,以及能自主的进行日常生活者(指70—88岁者)。理学检查无明显异常者,均属于被检之例。作者根
Phonocardiography in the elderly heart diagnosis and differential diagnosis, as well as heart disease hemodynamics and the disease course of observation and pathophysiology and other aspects of research, has some value. Phonocardiogram With the development of medical science, foreign countries have gradually been widely used in clinical medicine in recent years. Some domestic research units and clinical hospitals are also gradually carried out. However, up to now no standard (normal value) data of normal phonocardiogram have been seen in the elderly. Therefore, in order to understand the normal value and abnormality of phonocardiogram of the elderly, the author chose 200 seniors and chose the standard that the majority of the seniors have never undergone physical examination and have no symptoms. They usually participate in mental and manual work as usual , As well as those who can conduct their own daily routine (referring to 70-88 years old). No significant abnormalities in physical examination, all belong to the seized example. Author root
