“…Consistent with this, low HF-HRV has been shown to be associated with both SUDs and post-traumatic stress. For example, a recent meta-analysis found that alcohol dependence was associated with lower HRV (Quintana, McGregor, Guastella, Malhi, & Kemp, 2013), and a meta-analysis of seven studies found lower resting HF-HRV in individuals with PTSD as compared to healthy controls (Chalmers, Quintana, Abbott, & Kemp, 2014; Sammito, Thielmann, Zimmermann, & Böckelmann, 2015). There are several plausible pathways linking HF-HRV to SUD and PTSD.…”
