I had a biventricular pacemaker put in about 5 years ago when my his bundle pacemaker failed. I am just curious about how they got a biventricular pacer approved and paid for by my insurance. I had thought that you needed to have a certain degree of heart failure and a low ef (neither of which I have) to get these devices approved for implantation. I do pace over 90% in the ventricles and I am young (44), so I wasn't sure if something like that could get approval alone for this device. But as I've been reading up on it, I have never read about anyone who has received a crt device based on that. Just curious, if anyone else has a bi-v and recieved it just because they pace a lot in the ventricles.
