Analysis of heart rate variability in posttraumatic stress disorder patients in response to a trauma-related reminder

Favouring emotional processing in improvisational music therapy through resonance frequency breathing: a single-case experimental study with a healthy client

“…There is, for example, strong evidence suggesting that the practice of meditation results in an increase of (relative) HF power (An, Kulkarni, Nagarathna, & Nagendra, 2010;Krygier et al, 2013;Wu & Lo, 2008). Conversely, low HF would typically be the result of stress and anxiety (Cohen et al, 1998;Schwarz, Schächinger, Adler, & Goetz, 2003).…”

Cardiovascular and psychological responses to voluntary recall of trauma in posttraumatic stress disorder

“…recall without the presentation of reminders). A lower HR reactivity to the recollection of traumatic memories among individuals with PTSD, compared to that of healthy controls or other clinical populations, has been found in most of these studies (Cohen et al, 2000, 1998; Halligan et al, 2006). The study by Halligan and colleagues (Halligan et al, 2006), for example, has found that trauma victims with PTSD showed smaller HR increases (relative to baseline) compared to those without PTSD while voluntarily recalling traumatic memories.…”

“…Cohen et al, 2000, 1998; Halligan, Michael, Wilhelm, Clark, & Ehlers, 2006; Keary, Hughes, & Palmieri, 2009) have examined cardiovascular responses during voluntary recall of traumatic memories (i.e. recall without the presentation of reminders).…”

“…Among studies assessing HRV during voluntary recall of trauma, when reliving was not specifically required significant changes in HRV (relative to a resting baseline) were not found (Cohen et al, 2000, 1998). In contrast, when vivid recall of details was asked for, a significant decrease in HF-HRV was reported, and the reduction was greater among individuals with PTSD than healthy controls (Keary et al, 2009).…”

Integrating Cognitive Neuroscience Research and Cognitive Behavioral Treatment with Neurofeedback Therapy in Drug Addiction Comorbid with Posttraumatic Stress Disorder: A Conceptual Review

“…This heightened reactivity has been found across a variety of psychophysiological measures during presentations of trauma-related auditory or visual cues, and during personal imagery of traumatic events (Grillon et al, 1998;McNally, Amir, & Lipke, 1996;Sahar, Shalev, & Porges, 2001). An abnormal state of autonomic balance, assessed by the heart rate variability (HRV), which is observed in response to traumatic cues, has been considered to be one more characteristic feature of the PTSD syndrome (Cohen et al, 1998(Cohen et al, , 2000. Physiological reactivity on exposure to cues related to traumatic events is common for PTSD.…”
