A 30-year-old male asked:
Disclaimer

is there a long-term (30-day) version of an eeg that can see if someone has seizures? i've had mild to severe episodes of near-syncope, with occasional bradycardia/sensations of pauses, followed by shaking. so far nothing has really explained it.

No: There is a 30 day recorder for cardiac arrthymias but not EEGS. Make sure you see a neurologist for any thoughts you are having seizures. If you are having bradycardia you may need to be checked for any arrhythmia. Have you visited your doc for exam?

My impressions: The most useful EEG is a 3 day ambulatory study, or a 72 hr test. An inpatient monitoring ward stay can go for 48-72 hrs, and might be a useful approach. Your description does not sound like epilepsy, but more like either syncopal tendencies or even panic attacks. Maybe get opinion of a local psychiatrist and neurologist before further testing.

Cardiology: It's far more likely that you have a cardiac issue rather than an epileptic issue. Have your PCP send you to a heart doctor for further evaluation and potential longer term cardiac monitoring.
