On Friday the 7th I had a heart cath. I felt strange in a few minutes, in chest..and felt I was falling. I was awake for the procedure, however, I opened my eyes, and a nurse was on each side of me, feeling for pulses in each side of my neck. The one on the left, asked, "Are you OK?" I said, "Why?" They had to shock my heart back into rhythm. Is this normal? I asked why my chest was burning, they said they I blacked out, and they had to shock my heart back into rhythm.
