Suggests QTVI as possible acute marker of autonomic change post-concussion; hypothesis-generating and requires prospective validation before clinical use.
Does recent concussive head injury increase QT interval variability in athletes?
Vagal cardiac autonomic modulation, measured by QTVI, is transiently impaired within 48 hours of a concussion in athletes, suggesting potential utility as a noninvasive marker for acute concussion.
Fountaine et al. (2011) studied this question.
