Brief summary: The ANTHEM-HF Study is designed to demonstrate the safety and efficacy of vagus nerve stimulation (VNS) with the Cyberonics VNS Therapy System for the treatment of subjects with symptomatic heart failure.

Detailed description: Heart failure patients will be enrolled and randomized to cervical VNS implantation on either the left side or right side. After a 2-week post-implantation recovery period and a 10-week stimulation titration period, continuous periodic stimulation will be performed for 6 months, with data collection at 3 months and 6 months.

Eligibility criteria: Inclusion Criteria:

* Patients with symptomatic heart failure, New York Heart Association (NYHA) class II/III with reduced EF and dilated hearts
