I did have the test. I passed out right away. I have the neurocardiogenic syncope. I had passed out twice and I didn't know what was wrong with me. No alcohol, stay hydrated, check your blood pressure (ensure that isn't too low), potassium and sodium. I was diagnosed a long time ago and at this point I have not passed out again. I used to exercise during the morning and at lunch. I believe that that was part of the issue. They sent my sodium pills that you get at CVS if I felt sick and my blood pressure was low.
