Disruption of bradycardia associated with discriminative conditioning in combat veterans with PTSD

Abstract: Abstract:The effects of combat-related posttraumatic stress disorder (PTSD) on heart rate (HR) responding associated with a discriminative delay eyeblink (EB) conditioning paradigm are reported. Combat PTSD+, Combat PTSD−, and Noncombat PTSD− veterans were assessed with psychometric self-report measures, and baseline heart rate variability (HRV) was measured before receiving a 72-trial session of discriminative EB classical conditioning. Two types (red or green light) of conditioned stimuli (CS) were used: one… Show more

“…The CES (Keane et al, 1989) consists of 7 items that assesses frequency, duration, and amount of exposure to combat. Veterans with a total CES score <8 were classified as non-combat, while those scoring ≥8 were classified as having a history of exposure to combat, as done in previous studies (Ginsberg, Ayers, Burriss, & Powell, 2008; Myers et al, 2013; Myers, VanMeenen, McAuley, et al, 2012). The 16-item AMBI and 18-item RMBI (Gladstone & Parker, 2005) assess current (adult) and retrospective (childhood) behavioural inhibition (BI), defined as a tendency to withdraw from or avoid novel social and non-social situations; AMBI scores have been shown to correlate with measures of anxiety proneness (Gladstone & Parker, 2005; Gladstone, Parker, Mitchell, Wilhelm, & Malhi, 2005) and with self-reported PTSD symptoms (Myers, VanMeenen, McAuley, et al, 2012; Myers, VanMeenen, & Servatius, 2012).…”

“…Due to repeated fear responses, cues related to the index trauma could function as unconditioned stimuli. However, evidence from heart rate conditioning paradigms has been inconsistent with regard to heart rate conditioning to non-trauma aversive stimuli (58, 59). …”

“…A minimum of 5-10 observations for each of the seven potential independent variables is recommended, which required a minimum size of 35-70 per MST status group and 70-140 combined (Ginsberg et al, 2008). The sample size was within the range required for multiple linear regression analysis for moderate and large effect sizes (Soper, 2010).…”

“…Both low HRV (hazard ratio = 1.8, 95% CI = 1.0-3.2) and high HRV (hazard ratio = 2.3, 95% CI = 1.3-4.0) measures from 10-second ECG recordings were strong predictors of cardiac mortality in elderly men (n = 2088) and women (n = 3184) (de Bruyne et al, 1999). In a study of combat veterans (n = 69), advancing age was predicted by HRV from 10-second ECG tracings (p < .01) (Ginsberg, Ayers, Burriss, & Powell, 2008). For several years, only the Rotterdam study reported prediction of mortality using 10-second ECGs (Hamilton, MacKechnie, & Macfarlane, 2004).…”
