That's wonderful that a COE for septal myectomies is in LA if you live near there. what is the name of the hospital that's a COE? That means they do many of these surgeries every year. I have no chest pain, others may. I initially had no pacemaker, about 3 weeks after surgery I started experiencing dizziness sometimes with vertigo. To make a long complicated story short, I got a pacemaker 4 months after surgery after my cardiologist and his colleagues figured out the reason. It's my buddy!
