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.

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.

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. ...Read more

Pots is a situation where there is an inappropriate heart rate increase to low blood pressure, but typically dont see more than just a sinus tachycardia. Sick sinus syndrome tends to have more abnormal findings on ecg. I am sure you have a cardiac specialist to whom these questions should be addressed. ...Read more

What is the most common cause of bradycardia?

What is the most common cause of bradycardia?

Medication: A slow heart rate can be normal in fit individuals at rest. Many medications, notably beta blockers, slow the heart rate. A slow heart rate can also be due to disease of the av node, which conducts impulses from the atria to the ventricles. This can be due to scarring from heart attack or aging, and is seen in some infections such as lyme disease and chagas disease. ...Read more
