Association between depression and heart rate variability in patients after cardiac surgery: A pilot study
Journal of Psychosomatic Research, 05/25/2012
Patron E et al. – The current findings extend the depression–reduced heart rate variability (HRV) relationship to the patients after cardiac surgery. Also, the study suggests that postoperative depression is more likely to be associated with reduced vagal modulation on the heart than with excessive sympathetic activity.
