First, I just want to say..I am not a doctor...I just feel that I have seen almost ALL of them. I was mis-diagnosed for 20yrs with epilepsy. Yeah bummer! I had about every test run under the sun. And I had the same problem you do. My pulse would drop way down and sometimes I would just black out.

They thought those were seizures. To make a long story short. I think EKG's are useless! Tell them to put a 24 hr to 1 week halter (sp?) monitor on you. They put a pace maker in me and I am fine now. Had my first regular EEG in 23 years. They had been testing my brain...it was my heart. I was on anti-convulsents all that time. And they kept increasing them! And they are the ones with the degrees??? Finally I went to MHNI Pain Clinic in Ann Arbor MI for Chronic Headaches and when I told them I didn't think I had Epilepsy...they listened and did more tests. Within 2 days I had a pacemaker. Good Luck!
