Thanks for your replys.
I have seen numerous Dr.'s about this and have undergone many tests. Nothing has been found. My cardio thought I might have Neurocardiogenic syncope, but my tilt table test was negative. I've also had many other cardiac & neurological tests. The last time this happened(in april)...I went to the ER and they ended up keeping me in the hospital for 3 days. I was hooked up to telemetry the entire time and went through 2 stress tests, an echo, EEG, MRI, MRA, and went back the following week for a heart cath. I think it's pretty safe to say my heart is fine.
I just wish I knew what is bringing these spells on. Atleast it's not happening very often.
BTW, yes my blood sugar has been tested and is normal. My bp does run a little low...maybe this is part of the cause.
