That is one of the few articles I've found. I actually printed it out and took it with me to the cardiologist. I said I didn't have any sypmtoms, but yes, I did have the feeling of passing out. The cardiologist still did not think it was
related to the heart condition, but it seems that patients with this had this in common. Beta Blocker has helped alot with the feeling of passing out. The dizziness I believe is from the med Zetia, for me anyway.

Do you have any experience with beta blockers? I'm finding more of a problem breathing now that i am on a full dose (25mg) than when i started with half the dose. I'm wondering if this is something that passes when first starting with a BB? Also, I read that they can make syptoms of emphysema worse, so I'm not sure what's causing the breathing problem.

Any insight on BB would be appreciated. Thank you!
