摘要
利用微型计算机、心电放大器和A/D卡,配以功能丰富的软件系统,实现了心电向量图的彩色分时显示、参数计算、快速打印,克服了早期心电向量图泪点密集、误差大的缺点,并着重从软件方面阐述了系统的实现方法。
The use of microcomputer, electrocardingram amplifier and A/D card, with multifunctional computer software system, achieves the display of colour vectorcardingraphy time-sharing, parameter calculating and high-speed printing; overcomes the former concentration of vectorcardiography lacrimal point and high inaccuracy. This paper elaborates, the operating methods of the system empbatically on software.
