Heart rate and heart-rate variability (HRV) were studied through a set of different methods in high (highs) and low hypnotizable subjects (lows) not receiving any deliberate hypnotic induction in basal conditions (simple relaxation) and during nociceptive-pressor stimulation with and without suggestions of analgesia. ANOVA did not reveal any difference between highs and lows for heart rate and for the HRV indexes extracted from the series of the interbeat intervals (RR) of the ECG in the frequency (spectral analysis) and time domain (standard deviation, Poincare plot) in both basal and stimulation conditions. Factors possibly accounting for the results and likely responsible for an underestimation of group differences are discussed.
在基础条件下（单纯放松）以及在有无镇痛暗示的伤害性压力刺激期间，通过一组不同方法对高催眠易感性受试者（高敏组）和低催眠易感性受试者（低敏组）的心率和心率变异性（HRV）进行了研究，两组受试者均未接受任何刻意的催眠诱导。方差分析未显示在基础和刺激条件下，高敏组和低敏组在心率以及从心电图心动周期间期（RR）序列中提取的HRV指标（频率域（频谱分析）和时域（标准差、庞加莱图））方面存在任何差异。文中讨论了可能导致该结果以及可能造成组间差异被低估的因素。
