背景：以往的研究表明，心率变异性（HRV）可能是各种适应不良心理状况的重要因素。方法：本研究对酗酒者（n = 49）和对照组（n = 45）的迷走神经张力进行了研究，以评估迷走神经张力介导的强直性心率变异性。结果：与对照组相比，酗酒者心率更快，想象前HRV暴露水平更低。当受试者暴露于虚构的酒精剧本时，观察到酒精组的HRV增加。补益HRV与消极情绪和慢性思维抑制呈负相关，与积极情绪呈正相关。此外，强迫性饮酒量表（OCDS）的强迫子量表与想象酒精暴露期间的HRV呈负相关。结论：研究结果与情感调节的神经内脏整合模型一致，该模型认为，功能失调的心理状态源于与低HRV相关的抑制机制受损。
Background: Previous research suggests that heart rate variability (HRV) may be an important factor in various maladaptive psychological conditions.Methods: This study was conducted to investigate vagal tone assessed as tonic vagally mediated heart rate variability in alcoholic (n = 49) and control subjects (n = 45).Results: Alcoholic subjects had faster heart rate and lower preimaginary exposure levels of HRV compared with the control group. An increase in HRV was observed in the alcoholic group when subjects were exposed to an imaginary alcohol script. Tonic HRV was found to be related inversely to negative mood and chronic thought suppression and positively to positive mood. Furthermore, the compulsive subscale of the Obsessive Compulsive Drinking Scale (OCDS) was inversely related to HRV during the imaginary alcohol exposure.Conclusions: It is concluded that the findings are in agreement with the neurovisceral integration model of affective regulation, which claims that dysfunctional psychologic states are rooted in an impaired inhibitory mechanism that is associated with low HRV.
