Event Description

It was reported that the patient had an episode where he experienced choking, and puking which he explained as a sensation that the generator was continually in magnet mode. He also reported a tingling sensation in his left arm associated with stimulation. X-ray images were reviewed and repealed no relevant information regarding the events. Additional clinic notes were received indicating that the patient reported that he experienced choking and shortness of breath sometimes. He felt scared during sleep. Patient complained of choking, shortness of breath, neck pain radiating left upper extremity. It occurred once in 10-15 minutes. In addition, he complained of pain in left chest and one episode of numbness in the left arm. The normal output current was disabled and magnet mode was left on. The physician notes that there was no abnormality on x-ray. The physician tried lowering the output current and adjusting the frequency, pulse width and duty cycle but the patient could not tolerate. Therefore the normal output current was disabled while leaving the magnet output current on. Patient has no symptoms when the device is disabled. No other contributory or casual events that preceded the reported events. The neurologist plans to refer patient to neurosurgery for a consult in regards to the electrode placement on the nerve. No known surgical interventions have occurred to date.
