A flexible program system for on-line analysis of pressure data from cardiac catheterizations is described. The programs are implemented on an IBM 1800 computer, equipped with remote oscilloscope/keyboard terminals. The current computer system can handle any combination of up to 4 pressure signals. During catheterization, measurement specifications (i.e. calibration levels or sites of pressure recordings) are entered via the keyboard immediately before each recording. As an option the whole expected measurement sequence may be stored on disk before the catheterization starts. This method will minimize the necessary interaction with the computer when the same catheterization procedure is used on several occasions. Changes from the predetermined scheme may, however, be undertaken before each recording to meet with unexpected events that may arise during the catheterization. After computer detection of calibration levels, the recorded signals are digitized during 20 seconds and analysed beat-by-beat. Calculated values are averaged and presented on the terminal oscilloscope in tabular and/or graphic form. The waveform analysis performed by the program system is validated in a statistical comparison between manually and automatically computed values.
本文描述了一种用于心脏导管插入术压力数据在线分析的灵活程序系统。这些程序在配备远程示波器/键盘终端的IBM 1800计算机上实现。当前的计算机系统能够处理多达4个压力信号的任意组合。在导管插入过程中，在每次记录之前，通过键盘立即输入测量规格（即校准水平或压力记录部位）。作为一种选择，整个预期的测量序列可以在导管插入术开始之前存储在磁盘上。当多次使用相同的导管插入程序时，这种方法将减少与计算机的必要交互。然而，在每次记录之前，可以根据导管插入过程中可能出现的意外情况对预定方案进行更改。在计算机检测到校准水平之后，记录的信号在20秒内被数字化，并逐搏进行分析。计算值被平均，并以表格和/或图形形式显示在终端示波器上。程序系统进行的波形分析在手动计算值和自动计算值的统计比较中得到验证。
