20例牙科焦虑症患者进行了调查，而坐在牙科椅在牙科诊所。记录患者暴露于牙科治疗场景以及Stroop注意力任务时的心率（HR）、心率变异性（HRV）和皮肤电导水平（SCL）。结果表明，与较长的手动反应时间（RT）的注意力偏差不一致的颜色词相比，以及威胁相比，中性词。与高HRV患者相比，低HRV患者对不一致词和威胁词的RT更长。此外，与基线相比，所有患者在暴露期间和Stroop任务中的HR均增加。与基线相比，暴露期间和S部队任务期间的HRV显示出降低。HR和HRV在暴露和Stroop任务之间没有差异。此外，HR和HRV在恢复期未恢复至基线水平。SCL显示从基线到暴露、从暴露到Stroop任务的增加和恢复期的减少。结果表明迷走神经心脏控制的重要性，在注意力，情绪和生理过程中的患者患有牙科恐惧。(C)2002年爱思唯尔科技有限公司All rights reserved.
Twenty patients with dental anxiety were investigated while seated in a dental chair in a dental clinic. Heart rate (HR), heart rate variability (HRV), and skin conductance level (SCL) were recorded while the patients were exposed to scenes of dental treatment as well as a Stroop attentional task. Results showed an attentional bias with longer manual reaction times (RT's) to the incongruent compared to the congruent color words as well as the threat compared to the neutral words. Longer RT's to the incongruent and the threat words were found in the low HRV patients compared to the high HRV patients. Furthermore, all patients showed an increase in HR during exposure and the Stroop, task compared to baseline. The HRV showed a decrease during the exposure and the S troop task compared to baseline. HR and HRV did not differ between exposure and the Stroop task. Moreover, HR and HRV did not return to baseline levels during the recovery period. The SCL showed an increase from baseline to exposure, from exposure to the Stroop task and a decrease in the recovery phase. Results showed the importance of vagal cardiac control in attentional, emotional, and physiological processes in patients suffering from dental fear. (C) 2002 Elsevier Science Inc.
