2个实验研究了心率在个体之间和个体内的可能关系，以及心率水平与心率变异性的两个时间指标之间的关系。在实验中1对18名正常男性志愿者的记录表明，自相关与心率水平之间存在线性关系，这一点得到了实验数据的证实。2、对1名S进行重复测量。提出了另一种变异性的时间测量方法(CVT)，它结合了RA和MHR之间的这种可预测的关系。这种自相关性与实验中任何注意到的行为或训练没有一致的显着联系。2，但CVT似乎确实与行为有关。这些数据并不支持这样一种假设，即静息心率和静息心率变异性(Ra或CVT)本身就是“唤醒”的可靠指标，而是两者都受到实验中通常无法控制的条件的高度影响。CVT与实验中在清醒状态下进行的脑电唤醒测量没有显著的关联。1.
2 experiments were conducted to investigate a possible relationship of heart rate among and within individuals and to investigate the relationship between HR level and two temporal measures of HR variability. In Exp. 1 records for 18 normal male volunteers yielded a linear relationship between the autocorrelation and HR level which was confirmed by the data collected in Exp. 2, in which repeated measurements from 1 S were taken. Another temporal measure of variability was suggested (CVT) which combined this predictable relationship between Ra and MHR. The autocorrelation had no consistent significant association with any noted behavior or training in Exp. 2, but CVT did seem to relate to behavior. The data do not support the hypothesis that resting heart rate and resting heart-rate variability (Ra or CVT) are reliable measures of “arousal” by themselves, rather that both are highly affected by conditions usually uncontrolled in experiments. The CVT did not significantly relate to EEG measures of arousal, taken during the wakeful state in Exp. 1.
