I have syncope that mimics epilepsy but IS NOT epilepsy. It lasts about 20-25 minutes and I drop with no warning. It started every other day and is now every 26-30 days with an increase of Toprol. Has anyone ever heard of anything like this? It is so odd to have a regular cycle...not related to menstrual cycle. I need help and can't find anyone anywhere who is familiar with this. I do have cfs and fm. It was caught on a holtor monitor and is called neurocardiac syncope ot vasovagal syncope. ???Waiting for someone to respond and keeping my fingers crossed. Thanks.
