将心电数据从文件中读取出来，并由声卡读入，从而发出心跳声，可将得到的声音作为模拟的心电信号-ECG data will be read out from the file, read by the sound card, which issued a heartbeat sound, the sound can be simulated ECG signal as

本文介绍了一个基于matlab和声卡的虚拟信号发生器的代码实现-This paper introduces a sound card based on matlab and virtual signal generator code realization

通过声卡输入放大后的心电信号，LabVIEW程序自动识别心率并显示-the amplified ECG signal is captured by a sound card. LabVIEW program automatically recognizes and displays the heart rate

将心电数据从文件中读取出来，并由声卡读入，从而发出心跳声，可将得到的声音作为模拟的心电信号(The ECG data is read out from the file and read by a sound card, so that the heartbeat sounds can be obtained, and the sound can be used as an analog ECG signa)
