Abstract

不安状態における自律神経機能を客観的に評価する目的で,指尖脈波を用いた心拍変動の分析を行った.対象は,不安状態を主訴に治療中の患者25名(男性6名,女性19名,平均年齢47.7歳).対照群33名(男性6名,女性27名,平均年齢48.7歳)であった.脈波測定装置を用いて低周波(Low Frequency:LF)成分および高周波(High Frequency:HF)成分を抽出し,LF/HFを交感神経,HFを副交感神経指標とした.心理指標としてはSTAIの状態不安と特性不安を測定した.不安群が対照群に比べ,副交感神経指標(HF)が低下する傾向が見られた.また,STAIと生理指標では,特性不安と副交感神経指標(HF)との間に有意な負の相関が認められた.以上のことから,不安状態における自律神経機能は,副交感神経指標(HF)によって客観的に評価できる可能性が示唆された.

This study focuses on heart rate variability to evaluate the autonomic nervous function of patients with anxiety (19 female and 6 male patients with an average age of 47.7 years). We measured the low frequency (LF) and high frequency (HF) components of heart rate variability using finger plethysmography. LF/HF was assumed to represent the activity of sympathetic nerves while HF was assumed to represent the parasympathetic activity. The results showed that the parasympathetic activity was lower among the patients than in the control group (27 females and 6 males with an average age of 48.7 years). The results also indicated a significantly negative correlation between trait anxiety (of STAI) and parasympathetic activity. These results support the use of parasympathetic activity, indexed as the HF component of the heart rate variability, in the objective evaluation of the autonomic nervous function of patients with anxiety.
