近十余年来,随着现代科学技术在医学中的应用,无创心功能检查方法得到蓬勃的发展。它与创伤方法相比有安全、可重复检查等优点。对于老年保建,早期发现心脏病患者及健康检查等更是创伤性方法不能代替的。用阻抗法或导纳法检测心血管系统的动力学指标,由于计算公式较多。人工测算极为费时,使这一方法在临床的应用受到很大的限制。若能用微机进行检测处理,对上述检测方法在临床中的推广应用一定会带来好处。我们选用价格比较便宜的AppLE—Ⅱ通用微型计算机和三道生理记录仪。把心电
In the recent ten years, with the application of modern science and technology in medicine, non-invasive cardiac function testing methods have been booming. It is safe and repeatable compared to trauma methods. For the elderly, early detection of heart disease and health checks and more traumatic methods can not be replaced. Impedance method or admittance method to detect cardiovascular system kinetic parameters, due to more formulas. Manual calculation is extremely time-consuming, so that this method has been greatly limited in clinical applications. If the computer can detect the treatment, the detection method in the clinical application of the promotion will certainly bring benefits. We use the cheaper AppLE-Ⅱ general purpose microcomputer and three physiological recorder. The ECG
