[Glossopharyngeal neuralgia with cardiac arrhythmias (author's transl)].Dtsch Med Wochenschr. 1975 Mar 21; 100(12):618-21.DM
In a 68-year-old female patient glossopharyngeal neuralgia of unknown origin occurred accompained by cardiac arrhythmias (bradycardia to asystole) and loss of consciousness. Subcutaneous atropine injections improved bradycardia but did not influence attacks of pain. Complete and permanent freedom from symptoms was established only after treatment with carbamazepine (Tegretal) 200 mg t.d.s.
