人与人之间疼痛敏感性的差异仍然知之甚少。考虑到疼痛作为一种稳态情绪的概念化，我们假设静息心率变异性（HRV），心率自主调节的指数，已链接到情绪和敏感性，随后管理的热疼痛的措施之间的负相关。收集静息心电图，并通过频谱分析得出HRV的频域测量值。59名右撇子参与者在暴露于4摄氏度的热疼痛刺激后提供了疼痛强度和不愉快的评级，并在三次暴露于降低的温度期间指出了他们几乎不明显和中度疼痛的阈值。更大的低频HRV与4 ℃疼痛不愉快的评分较低以及几乎不明显和中度疼痛的阈值较高相关。高频心率变异性与疼痛敏感性无关。研究结果表明，疼痛敏感性的影响，中央稳态系统的特点，也参与了情绪。(c)2007 Elsevier B.V.保留所有权利。
Between-person variability in pain sensitivity remains poorly understood. Given a conceptualization of pain as a homeostatic emotion, we hypothesized inverse associations between measures of resting heart rate variability (HRV), an index of autonomic regulation of heart rate that has been linked to emotionality, and sensitivity to subsequently administered thermal pain. Resting electrocardiography was collected, and frequency-domain measures of HRV were derived through spectral analysis. Fifty-nine right-handed participants provided ratings of pain intensity and unpleasantness following exposure to 4 degrees C thermal pain stimulation, and indicated their thresholds for barely noticeable and moderate pain during three exposures to decreasing temperature. Greater low-frequency HRV was associated with lower ratings of 4 degrees C pain unpleasantness and higher thresholds for barely noticeable and moderate pain. High-frequency HRV was unrelated to measures of pain sensitivity. Findings suggest pain sensitivity is influenced by characteristics of a central homeostatic system also involved in emotion.
