Cardiac Autonomic Changes After Thoracic Sympathectomy: A Prospective, Randomized Study [1]
Physiologic changes associated with sympathectomy for palmar hyperhidrosis were assessed in this randomized trial comparing T3 ganglionectomy to division of the sympathetic chain at T2 and T3. Outcomes were assessed using Holter monitoring. Clinical outcomes were similar between the groups. Electrophysiologic changes representing vagal activity measurements were more common in the ganglionectomy group.
