Pseudocholinesterase activity increases and heart rate variability decreases with preoperative anxiety

Abstract

Preoperative anxiety increases plasma cholinesterase activity and decreases HR variability.

Reactivity of heart rate variability after exposure to colored lights in healthy adults with symptoms of anxiety and depression

“…Some studies have reported no differences (Dishman et al, 2000;Hughes and Stoney, 2000;Shinba et al, 2008;Tulen et al, 1996). However, the most consistent finding is that anxiety and depressed mood are related to low levels of HF during exposure to stress (Hughes and Stoney, 2000;Ledowski et al, 2005;Light et al, 1998;Shinba et al, 2008).…”

Music Reduces Patient Anxiety During Mohs Surgery: An Open-Label Randomized Controlled Trial

“…Using a randomization table (a table of random numbers), eligible subjects were randomly assigned into one of two groups: a control group with no music or a treatment group that listened to the music of their choice during surgery. [17][18][19][20] The VAS is a horizontal line with a scale ranging from "no anxiety at all" to "extremely anxious." The STAI has been used extensively in anxiety-related research and clinical practice as a standard measurement tool for assessment of anxiety.…”

“…It has been reported that the one-item question adequately measures current anxiety and significantly correlates with STAI. [17][18][19][20] The VAS is a horizontal line with a scale ranging from "no anxiety at all" to "extremely anxious." The researcher orally instructed the patient in the following manner, "Please mark anywhere along this line to show how anxious you feel right now.…”

Effect of lecturing to 200 students on heart rate variability and alpha-amylase activity

“…In fact, Fuller (1992) has reported a reduction in heart rate, and an increase in LF and HF powers in low trait anxiety as compared to high trait anxiety participants. Ledowski et al (2005) have shown that anxiety is related to low levels of HRV parasympathetic components during exposure to stressors. However, the results remain debatable (Dishman et al 2000;Narita et al 2007).…”
