Reduced Heart Rate Variability May Indicate Greater Vulnerability to PTSD
A prospective longitudinal study of U.S. Marines suggests that reduced heart rate variability – the changing time interval between heartbeats – may be a contributing risk factor for post-traumatic stress disorder (PTSD). The findings are reported in the September 9 online issue of JAMA Psychiatry by researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System.
