High Cervical Spinal Cord Stimulation f or Unstable Angina Pectoris

Abstract
Twelve patients with grade IV unstable angina were treated with high cervical spinal cord stimulation (SCS). All patients had been previously treated with maximal tolerated doses of β-blockers and calcium antagonists and had no possibility of revascularization surgery or intraluminal angioplasty. Multipolar electrodes were implanted using a percutaneous technique, and the parameters of Stimulation were pulse width 0.1 ms, frequency 120 Hz, intensity that caused no unpleasant paresthesias, with two periods of 4 h ''on'' daily.
