A special-purpose analog computer circuit is described that, given a signal proportional to arterial blood pressure, generates signals equal to systolic, diastolic, pulse, and mean pressure at a calibration of 100 mmHg/V. Heart period and rate are also derived at calibration of 1 s/V and 100 bpm/V, respectively. The outputs are step-function beat-by-beat changes in these six variables suitable either for analog recording, or presentation to a panel meter for digital display.
本文描述了一种专用模拟计算机电路，该电路在血压校准系数为100 mmHg/V时，若给定一个与动脉血压成正比的信号，就能生成等于收缩压、舒张压、脉压和平均压的信号。同时，在校准系数分别为1 s/V和100 bpm/V时，还能得出心动周期和心率。这些输出是这六个变量逐搏的阶跃函数变化，既适合模拟记录，也适合显示在面板仪表上进行数字显示。
