“…The effect of neurostimulation has been linked to a form of sympathectomy [11,14]. Indeed sympathectomy is used to treat angina, and Apthorp et al [15] found that it relieved angina in about 75% of the patients. Since the exact causation of spinal cord stimulation is unknown, we measured the autonomic tone of the heart in patients before they were given spinal stimulation, to evaluate whether neurostimulation could give the patient an 'electrical sympathectomy'.…”

To determine whether spinal cord stimulation has any effect on the autonomic nervous tone of the heart, heart rate variability was used as an indicator of autonomic nervous control of the heart. The components time domain and power spectral analyses of heart rate variability were measured in 21 patients with angina pectoris. Twenty-four-hour Holter recordings were obtained before and after 12 months with spinal cord stimulation. No significant attenuation of time domain or spectral components of heart rate variability analyses were found. Apparently, spinal cord stimulation does not influence the autonomic tone of the heart.

“…In angina pectoris it seems that catecholamines exert an unfavourable effect on the balance between the supply and demand for oxygen by the myocardium. Since these observations a small number of cases of angina pectoris have been improved to some degree by cervical sympathectomy [3,7,25]. It is therefore reasonable to consider that a sympatholytic drug might improve patients with angina pectoris.…”
