为使了心功测定能在基层单位应用和推广,我们应用生物医学电子学的基本理论,研制了心功能测试输入仪。和单笔心电图机连接,可以记录心音图、脉搏图、心尖搏动图以及上述图形和心电图的迭加图。这样用1千元左右的心功能测试输入仪就可代替价格昂贵的多导仪。为了验证该仪器的可靠性,我们把迭加图与单一测量图、心电图机和多导仪测定的结果 In order to make the determination of heart function can be applied and popularized in the grass-roots units, we apply the basic theory of biomedical electronics, developed a heart function test input instrument. And a single ECG connection, you can record the sound map, pulse map, apex beat chart and the above graphics and ECG superimposed map. This use of a thousand dollars or so heart function test input instrument can replace the expensive multi-meter. In order to verify the reliability of the instrument, we put the superimposed graph with a single measurement chart, electrocardiogram and multi-channel instrument determination results
