电子计算机是一种进行数据处理和信息加工的工具,它具有运算速度快,存储容量大,计算精度高而且能自动连续工作等特点。由于医学科学的特点是数据多,涉及到的因素多且交互影响复杂。据统计,目前能辨认的疾病种类和症状有数万种之多,药物种类也不胜枚举。因此,电子计算机已经成为医务工作者的有力助手。自五十年代以来,随着医疗仪器的发展,其应用范围也与日俱增。医学应用概况生理信号的处理和分析大部分生理信号是以电信号形式出现的,如心电、脑电、肌电等,有些本身虽非电信号,但利用换能器可将它转化成为电信号,如呼吸次数、心率、心音、脉
An electronic computer is a tool for data processing and information processing. It has features such as fast operation speed, large storage capacity, high calculation accuracy, and automatic continuous operation. Because medical science is characterized by a large number of data, many factors are involved and interaction effects are complex. According to statistics, there are tens of thousands of types and symptoms of diseases that can be identified at present, and the types of drugs are numerous. Therefore, electronic computers have become a powerful assistant for medical workers. Since the fifties, with the development of medical instruments, its application range has also increased. Overview of Medical Applications Physiological Signal Processing and Analysis Most physiological signals occur in the form of electrical signals, such as ECG, EEG, and myoelectric. Some of them are not electrical signals, but they can be transformed into electricity using transducers. Signals, such as respiratory rate, heart rate, heart sound, pulse
