EFFECT OF SPINAL CORD STIMULATION ON CARDIAC SYMPATHETIC NERVE ACTIVITY IN PATIENTS WITH HEART FAILURE

We aimed at testing the hypothesis that spinal cord stimulation (SCS) reduces cardiac sympathetic nerve activity in patients with heart failure (HF). Patients with HF (NYHA -class III, EF ≤35%, QRS < 120 ms) were randomly assigned to SCS ON for 6 weeks followed by a 6-week OFF period, or vice
