12 blood-phobic subjects, selected according to the Fear Survey Schedule and the Mutilation Questionnaire, and 50 control subjects performed a paced respiration task during which heart rate and respiration were recorded. Respiratory Sinus Arrhythmia (RSA) was analyzed as an autonomic index of vagal influence on the heart. Analysis showed a larger RSA in the blood-phobic group than the controls and points to a difference in vagal activity at rest between the groups.
根据恐惧调查表和自残问卷挑选出12名恐血受试者，50名对照受试者进行了一项有节奏的呼吸任务，期间记录心率和呼吸情况。呼吸性窦性心律不齐（RSA）作为迷走神经对心脏影响的自主神经指标进行分析。分析显示，恐血组的RSA比对照组大，表明两组在静息时迷走神经活动存在差异。
