Can antidepressants cause autonomic dysfunction?

The potential for confounding of autonomic effects by antidepressants was clearly demonstrated in our own recent research on the association between major depressive disorder (MDD) and anxiety disorders and cardiac vagal activity and blood pressure (Licht et al, 2008, 2009b, 2009c), where we found that especially the …
