A heart rate biofeedback system consisting of a JPR 12 minicomputer (12 bit, 4 K), of input devices (an electronic circuit triggered by the EEG R-waves or a photoelectric ear lobe pulse detector and of output devices (a feedback indicator of successful or unsuccessful heart rate control during the preceding time interval, the teletype and the paper tape punch) is described. The actual heart rate is measured and compared with levels differing from the average by a preselected number of pulses/min. When a preset criterion is met, the levels are shifted automatically. In control session shuffled data from the preceding experimental session are used for feedback.
描述了一种心率生物反馈系统，它由一台JPR 12小型计算机（12位，4K）、输入设备（由脑电图R波触发的电子电路或光电耳垂脉冲探测器）和输出设备（前一时间间隔内心率控制成功或失败的反馈指示器、电传打字机和纸带穿孔机）组成。实际心率被测量并与比平均心率每分钟预先选定的脉冲数不同的水平进行比较。当满足预设标准时，这些水平会自动改变。在控制环节中，来自前一实验环节的随机数据用于反馈。
