  Purpose

The purpose of this study is to assess whether baseline sympathetic innervation in patients with chronic heart failure (CHF) is predictive for response to cardiac resynchronization therapy (CRT). And to assess whether response to CRT coincides with restoration of regional sympathetic innervation.
