Hello, I had a right heart cath with exercise to check blood flow with rate induced LBBB they told me I was in LBBB even before I started exercising, my EF is 40% & hasn't changed to 8 months. I feel like my general condition has declined & test confirmed I am in severe heart failure, so I have an appointment Tuesday to talk about a pacemaker, does anyone have similar experience? Will insurance pay even with the higher EF? I'd love to hear from others about improving quality of life with a pacer? Thank you!
