本文研制了一种以MCS8098为核心的多功能卡，与PC机组成一种完善的心功能检测诊断系统。该卡能完成心电、脉波、心音等信号的采集和预处理，具有EISA总线结构，通过并行中断通讯与PC机进行数据交换，由PC机分析处理相应生理信号，完成心功能检测诊断。
In this paper, a multi-function card with MCS8098 as the core is developed, and a complete heart function detection and diagnosis system is formed with PC. The card can complete the acquisition and preprocessing of ECG, pulse wave, heart sounds and other signals. It has an EISA bus structure. Through the parallel interrupt communication and PC for data exchange, the corresponding physiological signals are analyzed and processed by the PC to complete the heart function detection and diagnosis.
