本文采用APPLE-Ⅱ微型电子计算机通过自制的A/D转换接口电路与RM-6000八道电生理仪联接,计算出了27个心血管参数。输入信息仅为左心室内压、主动脉血压及主动脉血流三个生理量。软件部分由BASIC语言与汇编语言组合写成,共研制了6个模块即:A/D转换模块,数字滤波模块,自动确定心动周期模块,参数计算模块,高分辩率图形显示与打印模块和八笔彩色绘图模块。该程序并已移植到IBM-PC微型计算机上。本文最后给出了一次动物实验10个心动周期平均心血管参数计算的结果。
In this paper, APPLE-Ⅱ micro-computer through the homemade A / D conversion interface circuit and the RM-6000 eight electrophysiometer connection, calculated 27 cardiovascular parameters. The input information is only left ventricular pressure, aortic blood pressure and aortic blood flow three physiological quantities. The software part is written by combination of BASIC language and assembly language. A total of 6 modules are developed: A / D conversion module, digital filter module, automatic determination of cardiac cycle module, parameter calculation module, high resolution graphic display and printing module and eight strokes Color drawing module. The program has been ported to IBM-PC microcomputers. Finally, we present the results of calculating the average cardiovascular parameters of 10 cardiac cycles in an animal experiment.
