Before having an electronystagmogram you should know:
- At some centers you can't have an electronystagmogram if you have a pacemaker because the tool that measures eye movements can affect pacemaker function.
- Because an electronystagmogram can't find some inner ear problems, a normal result does not mean an inner ear condition is not present.
- To check for hearing loss or tinnitus, other tests such as audiometry or an auditory brain stem response (ABR) test may be done. If a tumor or stroke is suspected in a certain part of the brain, a CT scan or MRI may be used to confirm the diagnosis.
