摘　　要：设计了一种动态心电心音信号同步检测系统,对系统的整体设计方案进行了介绍,采用内置A/D的MSP430F149单片机和USB通信接口传输的采集系统进行同步采集、实时存储,并用VC++6.0开发了客户定征分析软件系统。最后经过临床验证,本系统误差小,实用意义很大。The synchronous detected system of dynamic ECG and PCG signal is designed in this paper. The software and hardware design of the system are presented briefly. The gathering system achieves synchronous sample and real-time store based on MSP430F149 with A/D and USB interface. And the characterizing analysis software is designed by VC ＋ ＋6.0. In the end, this system is verified by clinical datum, it shows that the error is small and the applicability is great.
