Clinical and electromyographic evidence of carpal tunnel syndrome in a hypertensive patient with chronic beta-blocker treatment.

We describe a case of carpal tunnel syndrome (CTS) in a hypertensive man on long term treatment with a beta-blocker, propranolol. The clinical and instrumental findings, including MRI at the wrist, excluded all other possible causes of CTS. The improvement in symptoms and electromyographic findings on discontinuation of the drug suggested that the CTS may have been related to the beta-blocker therapy.
