心动过缓和副交感神经活动增加通常被认为是典型的生理性厌恶反应。然而，关于厌恶对心率和自主神经控制的影响的研究结果是不同的。除此之外，除了心率之外，只有几项研究考察了心血管对厌恶的反应。这项研究的目的是利用阻抗心动图对伴随着厌恶的心血管反应进行区分描述。此外，它还将调查不同的心血管反应是否与特定内容的厌恶诱导有关。100名受试者观看了三部电影：一部中性影片(屏幕保护程序)，一部展示上肢截肢的影片片段，以及一部展示呕吐者的影片片段。后者分别被认为是与疾病和食物相关的厌恶刺激，代表了两个优越的厌恶领域。使用重复测量ANOVA比较了这两种电影的主观反应、皮肤反应和心血管反应。观察到对含有恶心内容的电影片段的强烈主观反应、皮肤反应和心血管反应。与疾病和食物相关的厌恶刺激的心血管反应在主观和生理参数上有所不同。因此，心率减慢只能被观察到是对与疾病相关的厌恶诱导的反应。观察到的差异被讨论为对特定领域厌恶反应组织的认可。(C)2008爱思唯尔B.V.保留所有权利。
A bradycardia and an increasing parasympathetic activity are often recommended as characteristic physiological disgust reactions. However, findings concerning the influence of disgust on heart rate and autonomic control are heterogenous. Apart from this, only a few studies examined cardiovascular reactions to disgust, besides heart rate.The aim of this study is a differentiated description of cardiovascular reactions going along with disgust using impedance cardiography. Moreover, it will be surveyed if different cardiovascular responses are associated with content-specific disgust-inductions.One-hundred subjects watched three films: A neutral film (screensaver), a filmclip showing an amputation of the upper extremity and a filmclip displaying a person who is vomiting. The latter films are regarded as disease- and food-related disgust stimuli respectively, representing two superior disgust domains.Subjective, electrodermal and cardiovascular reactions to these films were compared using Repeated Measures ANOVAs.Strong subjective, electrodermal and cardiovascular reactions towards the filmclips with disgusting content were observed. The cardiovascular reactions of the disease- and food-related disgust stimuli differed in subjective and physiological parameters. Thus, a decrease in heart rate could only be observed as a response to disease-related disgust-induction. The observed differences are discussed as an endorsement for a domain-specific organisation of disgust reactions. (C) 2008 Elsevier B.V. All rights reserved.
