Abstract

In this paper is described a comprehensive system, which can acquire heart sounds and electrocardiogram (ECG) in parallel, synchronize the display; and play of heart sound and make auscultation and check phonocardiogram to tie in. The hardware system with C8051F340 as the core acquires the heart sound and ECG synchronously, and then sends them to indicators, respectively. Heart sounds are displayed and played simultaneously by controlling the moment of writing to indicator and sound output device. In clinical testing, heart sounds can be successfully located with ECG and real-time played.

摘要

本文描述了一种综合系统，该系统能够并行采集心音和心电图（ECG），实现同步显示；并播放心音，使听诊和心音图检查配合进行。以C8051F340为核心的硬件系统同步采集心音和心电图，然后分别将它们发送到指示器。通过控制写入指示器和声音输出设备的时刻，心音被同时显示和播放。在临床测试中，心音能够与心电图成功定位并实时播放。
