摘　　要：【目的】研制一个计算机辅助的心血管信号检测和处理系统。【方法】本系统的硬件设计采用奔腾 Ⅱ / 2 33多媒体微机系统 ,多路模 /数转换器和心电电极、心音传感器、脉搏波传感器及由运算放大器等构成相关的放大器及滤波器。本系统采用可视化编程环境构建系统结构和功能模块设计的方法 ,基于多媒体技术和小波变换原理 ,在 32位Windows平台下 ,利用可视化编程语言VisualC + + 6 0和多媒体著作工具Authorware等进行系统的软件设计。【结果】本系统能完成心电、心音、脉搏波信号检测和处理 ,并将结果以图、文、声并茂的形式显示、打印或播放 ,还具有病案管理和心音听诊多媒体计算机辅助教学功能。【结论】它是一个新型的多功能心血管信号检测和处理系统。Objective To develop a computer-assisted detecting and processing system for cardiac-vascular signals. Method The hardware design uses a P-Ⅱ/233 multimedia microcomputer system, multi-channel A/D converter, ECG electrodes, heart sound transducer, pulse transducer, and amplifiers and filters consisted with operation amplifiers. The software uses structure and functional modular in the visual programming environment, based on multimedia technology and wavelet transform theory. Visual programming language Visual C++6 0 and multimedia design tool. Authorware are also used on the 32-bit Windows platform. Results The system can detect and process ECG, heart sound and pulse signals. It can display, print or replay the results in the format of chart, word and sound. It also has functions of patient record management, heart sound auscultation and multimedia computer-assisted instruction. Conclusions It is a new multi-functional cardiac-vascular signal detecting and processing system.
